I think what keeps this forum so close together is that everyone is so involved in POTCO topics. Allowing to many off POTCO sub-forum might just pull the attention away from POTCO and in a way separate users. It's a good idea to discuss everything but the forum must maintain it's meaning IMO. Right now there are 3 sub forum's that have nothing to do with POTCO and it's going great with those three. Good idea but i think it might have a bigger negative impact on the long run.
(assuming you were talking about a media section that does not have to do with POTCO... there's already on for POTCO)
