I've pretty much exhausted my good ideas for boosting activity with the writing contests I've been hosting lately. The WC isn't as much of a priority as other forums, so that's probably why it was moved down a spot on the main forum's index.
It may not be a bad idea to ask why some forums aren't getting as much attention as others, but I'm not sure if it would do any good. There's only so much stuff that people are interested in, and here it's mostly the TCG and VG stuff that were always meant to be focused on more than anything else (I usually don't dabble in things outside the Community Works anymore, though, so I might've just turned a blind eye to stuff).
