RE: Getting the right address. Something that is very hot on college campuses right now among the about-to-graduate is the practice of trying to obscure your name so that it won't come up when an employer searches for it. However, most students don't want to temporarily quit using their profiles or make it too hard for their friends to find them, so they are mostly making the changes easy to guess. "Ashley Johnson" becomes "Johnson Ashley", etc., or Sam Nelson becomes Sam Neilsen, and so on.
The thing is, employers now have the expection that a new graduate WILL have a FB page, and sometimes if they don't find one they will assume that it is being deliberately hidden. Therefore, they are using software to guess likely permutations and looking for those.
If you're going to assume an alias, make it a good one that is TOTALLY unrelated to your real name. Use the old ink pen in the phonebook technique if you have to.
