Where is Yahoo! Chat?

I remember back in the day when Yahoo! had an option in Messenger where one could join a chat room and talk to strangers with similar interests. There was a group for psychic interest, another for dating, another for religion or region etc. Needless to say, I haven't used the messenger for a while and I can't seem to find this option anymore. Does Yahoo! still offer this kind of activity anywhere? If not, could you guide me to where I can find popular chat rooms like these.
