As of recently, group chats have not been working.  Whether or not they have been taken down is unbeknownst to me.  Many people have been sending out emails with their screen names for yahoo or msn - who even uses those anymore?  I thought AIM ruled the chat industry.  Anywho, I created a page on facebook, which is open to everybody.  Facebook has over 60 million subscribers, so chances are that you are a member.  I would advise you to keep it clean and don't abuse the site.  The link is here  Facebok. 

Have fun!
