I have to be totally honest to you, What my impression on your gambling forum is that no one actually talks about gambling that often, I noticed that there is a low number of forum participants.
A post a month ago has no reply, threads are actually empty at all. I do not intend to discourage you with my comments, all you need to do is to attract potential participants for your forum who is related on gambling. About the website, I fairly like the layout it looks like the cryptotalk forum if you have seen it but the thick margin is annoying.
