iM@S2 subforum sounds good, since it's still a 2nd Vision game.
Honestly, there's a lot of disarray around here. We could probably have stood to organize things into 1st Vision and 2nd Vision with their own subforums, especially with 3rd Vision coming up. I've never really been a fan of having Shiny Festa under the iM@S SP forum. Likewise, it wouldn't be a bad idea to, say, split up the first game and L4U. But holy crap, that would be a lot or work to move that many topics around.
