Yeah, really. In fact, for all intents and purposes, you're looking at a non-profit site right now. (Well, at the very least, it's not-for-profit.)
And you know, it's not that we actually say, "You can find that here." The way it works: You submit your site, it goes into the database, user checks "Sites" for something he or she is interested in, and if they find your site, you've won out. :)
So! Hit the "Contribute" link at the top of this page and add your site!
