Why don't you try your hand at organizing it Ice? Just message the people that signed up before and ask if they're still interested.
Not that bad of an idea. We could actually organise one ourselves for the UC3 community. We could do a much better job too. If you were to wait till January I could front a $20 PSN card for each of the winners. If you wanted to host a SGC tournament for people, outside of SGC that is.
