I'm very sorry, but if you ask to be a forum mod, the answer will be no. I already have several awesome mods right now who do their job very well, and I don't need any more at this time. It's nothing personal, either, it's just that I choose mods based on when I need them, not how much I like them.
As for helping out, just checking the site regularly and contributing a lot is nice. Also, you can go here and see if there's anything you can do, which would be amazingly awesome of you.
Don't bother sending me messages or anything, I'm not in charge of the site anymore.
