Check boxes to display certain forums


Active member
I run a gaming forum with a lot of game forums, too many in fact. What I was hoping for, was a mod that allowed a user to use a series of check boxes at the top of the forum list, so that they can select "MMO, Action RPG, First Person, Third Person" or whatever, and that would display the appropriate forums.

I'd use something like this...

...however, most games belong in more than one "category".

Any suggestions as to how to go about this?
