Ive been going in there a few times a day for the past few weeks,and everytime i go in im the only one there,infact ive never seen anyone else in there,id really like to use it,but i dont think people go in there because:
1. I dont think people really know about it,i just noticed it was there about a month ago
2. Its kind of a pain to have to have a whole page open,even though you can float the chat window it would still be nice if it were floated all the time without an anchor page.
