I assume you mean the board that can hold multiple threads. If that isn't right, please correct me.
The board isn't very active now, but there are a few people still trading in AC:GC. There also isn't a limit to the number of boards that ACC can have, so it isn't hurting anything. The only times I've seen boards be removed is when they are combined. For example, there used to be 3 or 4 different AC:GC trading boards, but having that many boards split up the already small traffic, so they were combined to keep all of the AC:GC trading together. There really isn't anywhere else to put AC:GC trading threads.
Let's go Gophers! Ski-U-Mah!
Sorry, I don't accept random FCRs.
