Design:
You haven't really done anything to it. I suggest first making your own color scheme. I notice you use orange, which doesn't match with the default blue scheme, but if you made your scheme based around orange and maybe grey, you can get some good results.
You are also starting off with too many forums. Condense it down to about 10 forums and add more when you get more members. Less forums makes your forum more appealing to guests.
