We don't have enough traffic to support a bunch of different forums. It was confusing for people to have multiple forums with potentially overlapping topics (The Open: where any topic is open, except politics?). There were too many opportunities for posts intended as non-political to turn political. It just means we run two "political" forums.
At the end of the day, it's a Notre Dame site, and the Open is here to keep the non-football talk off the football board. The Open gives ND folks the chance to talk about other topics together, but it's not really our purpose.
