Need suggestions for my new forum.

When i am here i always see the "Other game sales" category. I always see that there is not much support for this, I always think that they should have separate things for different things...

I thought i was going to make a black market where you can trade accounts and gold for a different game, and a chose maple story.

So now i have the forum set-up and i need some feedback.

So, please tell me what i can do to the site to make it better for other people, or, if you have an account you never play on, sell it
