I think Yop asked about this not too long ago. We're just making sure the forums are ready with discussions already taking place before we decide to make it public. From the looks of it, we're close, if not already set to make it public.
We still have to create the layout. I believe Yop will be working on that when he can be arsed.
Compilation General, Before Crisis, Crisis Core, and Final Fantasy sections need more activity. But, it's not that big of a problem since the boards are still fairly new.
Clearly, the forum still needs some work, but it's ready to go public, imho.
