Well perhaps nothing can be done about the indy manu forums. You can ask them if they still want to have one open since 1 post every 2 weeks doesn't generate a good flow of Q/A & commentary for the manu.
About the others, I'm jsut making a suggestion. There are a lot of foums on this board, but I don't see a lot of active discussion in all of them very often so I'm just thinking to generate more discussion, you can consolidate some. Just a thought.
Not a knock on the board so please don't take offense.
