I don't use it because I can't. I've tried several times and can't get in. The one time I did get in, no one would acknowledge me. So I figured either they weren't interested in "chatting" with me or they couldn't tell I was in there. Either way it doesn't work for me. I've tried all the posted suggestions for getting in using other software, and no go.
So, I don't go.
That was some time ago, but I'm just not interested now 'cause it was so much work and so dissappointing.
