Your application has been noted. Thank you for your willingness to help! Ideally, I'd prefer to have people moderate one or two individual boards, rather than entire groups of them. That all depends on how many people step forward though.
I will agree that as a group, the locals are popular, with Dwilight being the most popular, but general discussion and feature requests are busier as well. The forum itself keeps it's own stats here, if your curious:
