I doubt it's going to work, I really do. This forum is far too popular for the users to just switch over for an alternative. This forum offers active users who will give an answer quite quickly. You'd need a lot of users to be active on your forum to keep it afloat, this will be hard.
The main idea of your forum is to offer an alternative to this section? The only problem is if people went to your forum, they'd be insulted and made to be idiots as you quite clearly admit, Denta.
I'm not trying to create an argument but just pointing out things I think will make it unsuccessful. It's worth a shot but it's like me trying to compete with WHT.
