Play it safe. Rough language, risky pictures -- even having an account under another name -- can hurt you and anyone else who's in those questionable photos with you. Once you've tidied up yours, ask your friends to take anything off their pages that makes you look iffy. After that, search for yourself on the web, and see what's there. You might not need to address it or be able to do anything about it, but it's better for you to know before the colleges do.
