TheWell, I work for a school district and we actually had to sign a contract stating we would not befriend students on Facebook. They take it seriously!

As far as the OP, what is your purpose for "tracking down" your T? What would you do with that information? I don't see how it could be of any GOOD value to have.... I agree, this sounds like stalker-ish behavior (or wanna be anyway)...and I probably wouldn't open up that can of worms if you want to stay with your T. Heck, ask them where they live...see if they answer.....even a general neighborhood or whatever.
