You can find the originator of the chain letter at the bottom. I remember him. The "UC" designation stands for "User Consultant," given to student volunteers helping people in the old EECS terminal room (38-344, I think). I had started a few months earlier, and was still learning my way around campus computing, networks, etc. I hadn't started my UROP yet; hadn't even met anyone in the LCS group. In fact, I was still somewhat undecided about what my major was going to be at the time. (Not a good idea for someone in his junior year.)
[Update] Just found a complaint about the chain letter.
