The forum is good in terms of being simple and responsive. Aside from that, nothing is so special but I understand since it's only new. I think you should have improve it more. Don't require users to sign up before seeing the content of your site. It would be better if we can see what sections of forums do you have, what new there, and some interesting stuffs for us to be encourage not just to sign up but really to be an active member of your forum. Another thing, I saw that the forum only has 1 post so far, I think you must have some posts there as admin, so that when someone signed up, they can read something. It should start with you imo.
