Actually... we may just want a different look for this forum.
As said, it'll be difficult to beat Bitcointalk. It has history, it has great info stored in it and it has great and helpful members. What does your forum have? And if you'll tell me that you have nothing, but it's better packed that's not enough.

Sorry if I'm too harsh, but I've took a quick look there and:
1. The topics are about... anything. And it's not really structured.
2. It looks more like blog posts with comments than a forum. And the name also suggest this.

You seem to advertise a general purpose blogging platform as crypto forum... here. Ummm... no. That won't work.
