pish tosh, blue!
not only should you friend her, make certain that you invite her to take all of those facebook quizzes....such as "what kind of animal am i" or "what is your pornstar name"...adcoms LOVE that *&^%!
in addition, make up a group entitled "why i love (whatever school she is an adcom of)" and then invite her to join that one, too. better yet, make her an officer of that group.
finally, and this is very, very important, make sure you send her numerous IMs...it will make her feel both loved an appreciated. tell her about your day, what you had for breakfast, really let her get to know the REAL you...it will pay big dividends i assure you, and absolutely NOBODY will think you are a creepy stalker.
