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.
Lots of gambling forum had failed up in the past when it comes to traffic.Come to think that there were specific forum specially on famous gambling site stake
which has
https://forum.stake.com/ in means of discussion where its normal for it to be tied up with its popularity.You can see significant amount of activity. - This is an example.
Its not needed to have a gambling site but you do able to see the advantage.
