All of us? That might take a while...
Depends on how many people you could meet in a minute. If you could meet five people in every minute, and kept meeting five people in every minute for as long as it took to meet everyone, that would be... 11.684 hours. You might want to get a good night's sleep and a very hardy meal before starting.
As for knowing each other, I believe some members of the forum know some other members in person, but I don't think it's very many. Of course, I'm pretty new as well, so I wouldn't advise taking my word as true without a doubt.
I guess since you told us your name and stuff, at least a few of us should reciprocate... I'm Evan, I live in Benicia, California, USA, and I'm fourteen. I've only been dancing for three years or so, but I love it, so much so that I'm putting off doing my French and Geometry homework just to check this forum
. I hope you settle in and have fun meeting us all and discussing various dance-related topics with us all. I was going to put something here about this thread being moved to the "What's new on criticaldance" forum, but I guess I was beaten by another insomniac techie, and this one with administrator privileges.
