Microsoft Warning as well as SIGN UP warnings
I do like that idea.
Anyways so I'm signing up for hi5, bebo, orkut, mixx, digg, etc... and doing all the registration blah blah blah. It took about 30 minutes or so...then, Wham...
I'm getting these emails the next day like hey what's with the internet sites blah blah..and I'm like...what are you talking about? and then, i'm like hmmm... apparently it sent out something using my address book BUT it didn't ask me. My friend said it might be a pre-click thing--like it's clicked already... WT...
so be careful.
I just updated my windowslive and this time, I was looking for it. They had something to make my search engine yahoo or something like that--no msn... and I was like HUH? and it had words like this would preclude any requests to change... I'm like... MAN Heck no.. WT... and so now I'm looking at everything, it wanted to make my default email windowslive which is no problem, but it also wanted to make msn messenger my default. um... I only have two friends on msn messenger.
so words--BE CAREFUL WHEN YOU SIGN UP FOR FREE STUFF.

A question about formations and strategy from a fan
Date:
Feb 10, 2009
Message:
I want to fist say thx for your advice last time it was really helpful. but i have a few more questions to ask. when i play doubles with my partner we are very different but we work well together. He has the sharper vollys while i have the more powerful vollys. he has a big flat serve, but his spin serves are not very good. i have a big flat serve to but neither of ours are consistant, so i use a topspin serve during doubles. i swich it up between slice and topspin and sometimes flat.
i have a much more powerful drive and baseline game but he is somewhat more consistant. i move a lot to run around my forehands while he uses a good two handed backhand.
do you know what formation or statagys we might use. We randomly choose who will be which side when reciving.
we are both very aggressive and attack orientated but sometimes its up to me to be defensive cause he won't.
any advice?
is it better if you're on the ad.
i have a partner who hits a great inside out on the ad side. he rarely misses it. we tried switching with him on the fh, but it's pretty normal on that side. he hits the forehand and ends up just rallying with the other person's forehand, But when he plays the ad side, his forehand goes to the backhand, he has a great slice crosscourt backhand, and a very good overhead.
so my answer:
can your partner hit the two hander away from the net person from the deuce side? if he cannot, have him play the ad while you play the deuce. when you play the deuce, hit all forehands. you run around everything and just nail it crosscourt mixing in some down the lines.
you play the spin game so your serves are different from your partners mixing in an occasional flat serve--all your spin serves aim it to the backhand of your opponent 80% of the time. same thing on the replies, you just hit all forehands. it's half a court. hitting a forehand should be kind of easy. if you get a backhand, can you lob? or slice it away from the net person?
you can play one up and one back. it's the easiest. if you can both play up at net, do it. but if worse comes to worse, play two back on the first serve, and move up on the second. alot of pros are doing that now.
good luck

Roger--a great article
STOPPAGE TIME
Men don't cry, but when Roger Federer does....
By Tulsathit Taptim
The Nation
Published on February 4, 2009
I WASN'T much of a Roger Federer fan. Well, that was until the Australian Open tennis final three days ago. Until AFTER the final, to be exact. In fact, as an admirer of Pete Sampras, whose astonishing record of 14 Grand Slam titles is in danger of being broken by the Swiss player, I was quietly hoping Rafael Nadal would put Federer to the sword on Sunday, which is what happened.
When Federer's last shot sailed long to give Nadal the elusive Australian Open title, I was satisfied. But I had no idea what was to follow. I had no idea, most of all, that tears could also be a man's most powerful weapon.
Don't get me wrong. I liked Barack Obama's presidential inauguration spectacular, and I thought his speech was inspirational and simply great. But boy, maybe only Roger Federer can sweep you off your feet with just a couple of sentences and a couple of teardrops.
The tennis showdown was up there with the best sporting encounters in history. But to me, the real "moment" of the Australian Open final came after the match was over. And it wasn't even when Federer tried unsuccessfully to fight back tears. The guy is well known for crying easily and his fans are no strangers to his outbreaks of emotion. This time it was rather different, though. His were not tears of joy because he was on the losing end of a major final he wanted so much to win. He approached the microphone during the trophy presentation ceremony trying very hard not to cry. He even said a few words to loosen himself up and distract his own heavy heart. When someone in the audience shouted, "We love you!", his efforts at self-control were in vain.
Speechless and choked with emotion, there was no way in the world Federer could utter a word to the crowd without crumbling like a heartbroken schoolgirl on her best friend's shoulder. The organisers decided to let him retreat and have Nadal, the winner, address the spectators first. (For a few seconds I had this scary feeling that Nadal, who was looking emotional himself, might be infected and break down, too. That would have turned a beautiful, touching moment into something a bit ridiculous. I mean, two heartthrob athletes crying at the end of a Grand Slam final? That would be one man too many.)
But Federer, who started it, rescued it. And he did so graciously. As the organisers were looking rather awkward and unsure after handing Nadal the trophy, Federer stepped up toward the microphone. "Let me try again," he said. "I don't want to have the last word; this guy deserves it."
With that, he had me. What can I say? We have all been in situations where everyone wants to have the last word and opponents are there to be humbled, not respected. Federer showed us the soft side of a man and his sense of sportsmanship and fair play at the same time. It's easy to praise your rivals when you are on the winning side; handling a devastating defeat in such a manner is different.
The five-set Australian Open final took our breath away. Federer was absolute tennis poetry in motion, and Nadal's extension of his mastery of clay to other surfaces continues to amaze the world. It was the kind of game you didn't really want either man to lose; a classic clash of different skills that were equally superb; a demonstration of unbelievable composure and stamina; and a great example of what healthy and constructive rivalry can give us.
Without Federer, Nadal would not be where he is, and vice versa. That must have been the thought on Federer's mind when he decided that, despite the trophy and fan's deafening roars of approval, Nadal's deserved honour would not have been complete without the most important element - true respect from his fiercest rival.
Like someone said, the two players are becoming the best things in tennis since the racket itself. That's surely arguable, but we can't take anything away from the touching and inspiring drama that happened after the game. For more than four hours, the two men played like battling angels unleashing balls of fire against each other, nothing on their minds except victory at the other's expense. But in the end the rivals became a pair, and glided down to earth to show us the good side of human beings.
