It's up to Barry what happens to the forum, but if he wants them to be more active, I think the best course of action would be to make the forum it's own thing that talks about gaming in general. Sega and Segabits could still have it's sub category, but opening the forum up like that could do wonders and also bring more traffic to the main blog.
The big issue for that mind, is more time for promoting and designing etc would be needed to run the new forum.
