At the moment we have one sub-forum for MMHK, one for Guild Wars etc ... in order for a forum to become active there needs to be enough interest, it to be created and then to know who plays that game (and for them to realise the forum's there).
Might it not be easier to streamline this into having a single hidden Games Forum which all active members are members of to merge MMHK, Guild Wars etc ... and then if say someone wants to create a discussion for any other game it is the simple matter of creating a thread for that one rather than the rigmarole of an entire forum created just for that purpose?
