I'm not suggesting one big forum, like GMK. Rather, three different forums (Sky Blues/General Discussion/Site Stuff), with the Sky Blue forum having, at max, two sub-forums (Sky Blue Chat/Matchday talk). This would be modelled on a successful site like
http://www.the-wolf.co.uk. Doing this substantiates one forum, instead of spreading the bases thin.
Stuff like speedway, rugby, ice hockey or whatever else could be discussed in one of the General subforums (e.g. Newbies/General chat/Politics/Other Cov Sport etc). So basically make it a "top heavy" forum, with Sky Blue Chat being the big beast, and loads of little sub-forums beneath that unrelated to CCFC.
