Just thought id let everyone know as this has come up twice.
You cannot use anything like @ < > %, etc in a social group name. It will kill the group. Only standard letters. You also cannot use works like "and, for, or, of, the"
These are all words that are stripped from the name tag of the thread
Ie. "for the love of house music" will become love-house-music.html" which the forum software cant find.

Thanks
