Alright, so I was just trying to start a thread in Chit Chat. Now it says "Must Select a Thread Prefix", just like it does when you start threads in the LGBT News section. However there is no option box to actually choose a Thread Prefix when starting a thread in the Chit Chat section. And none of the other threads in Chit Chat have a thread prefix, except for one thread that a moderator manually added a "PG-13" prefix to a short while ago.
I'll poke around and see if I can fix it, I was flying by the seat of my pants a bit. Okay, for now I've removed prefixes from the Chit Chat forum. I'll leave it to one of the more techie admins to set it up so that prefixes are optional.
Seems to be working now, thanks! The problem was that there wasn't that little box to even choose a prefix, thus it was impossible to start a thread at all. :eek:
