I just searched "year" under the Screenshot of the Week forum, and it gave me about 5 pages of results, ranging from just having the word year posted somewhere in the thread, all the way to finding the SotY topics. I think they should be run the same way that SotY goes, where 3 thread get made for 4 or 5 screens, and the winner from each moves onto SotD.
