Being a ROM hacker, but suggestions revolve around that area:
1) Perhaps you could have a tools and tutorial sections here.
2) Some stickyed threads for general help could be added if you want to.
Overall, the site is decent.
I'm GKS (known as G.K.S. on PC). I'm a hacker (a scripter to be specific) and I'm learning some other programming languages at the moment as well. I found this forum through someone's signature (SCV's signature).
