I think Alex has the best idea. More forums and subforums (sorry admins).
I must disagree on this point folks. I, like a few of the usual suspects here, enjoy hanging out on EDCF as well as here. My issue there is that there are SO MANY subs that I actually find it quite difficult to find what I'm interested in. I know, doesn't sound like it makes much sense, but here, with just a few forums, I scan subject lines and open the threads that sound interesting, instead of scanning 30 subs, and seeing what looks interesting today...oh wait, I already opened this sub...now, did I skip one?
I like the format ETS has now.
