The new forum would just have support posts from other users and the author's responses while the release forum would have have release and updates information (and anything else that is important). Each mod would have one thread in the new forum (like it does now in the release forum) but this thread would only be for support. Might want to reread my post again since I though I had made that part clear... perhaps I didn't.

Here's an example:
- MOD Release Announcements (forum name)
--
[2.05] Link Mod (thread name)
--- initial post by JohnAbela (1st post in thread)
--- update post, updated to version 1.1 by JohnAbela (2nd post in thread)
--- important info from author by author (3rdpost in thread)
--- update post, updated to version 1.1 by JohnAbela (4th post in thread)
--- etc
- Official MOD Support (forum name)
--
[2.05] Link Mod (thread name)
--- initial post by JohnAbela (1st post in thread)
--- post by joe user 'i need help' (2nd)
--- reply by author 'fix this' (3rd)

--- reply by author 'fix this' (5th)
--- etc
