How about just changing the default so when the new people and guests log in, it dumps them in sex chat rather than into the adults room. That's what 90% of them want anyway. I'm guessing most of the regs do what I do, have a desk-top shortcut that takes me to the room of my choice so it bypasses the 'default'.
I do like the idea of a members only room though.
It's not exactly a room, per se', but the ability to 'conference' several friends into one PM at the same time would be nice if its not possible to have 'private rooms'.
