Yeah, we have a perl script operating for it, but I'm not sure if it keeps track of periods longer than a month.
By the way, I think we may just feature affiliates and stuff on the Links page, and maybe stick the links page in some unused corner of the site. Having a bunch of flashy ads under the left sidebar would ruin the scholarly, clean, and orderly feel. Plus, we're going to be the ultimate site anyway, so those photoshop expert guys with zero content can come to us.
