So I was a member of this Zelda related forum for about 2 seconds once and I remember something neat they did. When you reached about 100 or something posts you were sent a quiz and depending on the results you would be placed in one of the three groups. Gannon - Power. Zelda - Wisdom. Link - Courage.
I was thinking, how difficult would it be to do something like that for this site? I see it is getting quite large and with the release of Diablo 3 I can just see it getting bigger. This would let everybody post in the current sections but would create three or four or five or however many new sections, and depending on what your quiz results were, you would be placed in one of the groups and one of those new sections would be opened to you.
Just an idea, might help create camaraderie, and then friendly group rivalries and whatnot.
Not segregation per-say. More along the lines of each group getting an additional section fo their own that they can post in and talk among themselves while still having access to the forum that we know today.
