i think all the clubs are pretty much open to incoming freshmen, actually, in the first two days of class we have an involvement fair, which is in the hub which i was talking about before, which, all the clubs and organizations will line up in a huge hall with their booths and you can literally just walk up and down the aisles and sign up, get your name on listservs, and they'll email you when their first meetings are, and whatnot.
