hi there, great idea for a bit of fun! i have regular cam chats with friends on line, but most people only have msn, so a get together on sounds great.
i think that if you try and create a room you will get some drifters from cyber world popping in though.
one way would be to arrange a time to get together, and maybe for one person to collect the addresses and then send them to the rest of the group perhaps? just and idea, hope it goes ahead one way or another...
