If you were looking for the missing user rooms they are gone
But
www.yahlist.net has listings of where people hang out
For example Indiana:15 is the Indiana Gay/Bi Room
Along with these "hangout room listings"
www.yahlist.net has a bunch of
Yahoo Group Chat rooms listed and how to get into them
For example They're are several Goth chat rooms that are run
under the Yahoo Group Rooms and are not in any directory
except Yahlist.
You don't have to become a member to get into these rooms there is a command that can get you in from yahoo messenger
