Umm...lesse...First you have to understand that the state of Maryland is very poor right now, so poor that the new governor is trying to allow legalised gambling, although the legislature will never allow it...Anyway, I went there to do research in AI over the summer instead of at MIT, as my gaming group is all down there, so we only get in good games during the summer. So, they figured out that they could pay me less if I was a faculty member, and they didn't have to pay me as a student researcher since I wasn't a student there. So I became a faculty researcher. Not something that happens every day, I guess, so its not some arcane American custom that they've been hiding from you
