Thanks, everyone, for your advice and ideas!
I emailed one off the other day, but the position was already filled.
If it's filled, PLEASE take it off of the website!! I snail-mailed three more today. I have more to get out there. I got copies of my resume and my CV. I also got some envelopes to match my resumes (not the CV because I don't send that out as much; I'll get envelopes as needed). I even broke down and bought a book on cover letters. Normally, I get one from the library or use a friend's, but I figure it's an investment. Needless to say, I spent a grip of money today at Kinko's. Hopefully, it will all pay off.
