I agree wholeheartedly with the previous posters. Perhaps she is trying to send you a vibe through the cosmos. Especially if you know how to contact her, but she doesn't know how to contact you. I think a simple letter would be a lovely way to say "I'm thinking of you" without requiring a response. That way she may chose to ignore it, or she may be delighted to hear from you.

That said, an old friend messaged me on classmates.com a while back. I replied right away, eager to talk to her. She never responded to my reply, and I was heartbroken. It was much worse then if she'd never messaged me at all. So if you do write her, please be prepared for a conversation via whatever mode you chose for communication.
