Should I add this girl on Facebook?

[K]

There's a girl that I like. We both are members of the same GSA on campus. I have been to three meetings in which she was there, but I have never actually personally spoken to her. Before each meeting we go around and introduce ourselves so I guess you could say that we have indirectly met. We always give each other "the look" though. I'm thinking I should make the first move. I want to add her on Facebook, but I am wondering if this will come across as creepy or awkward? I probably won't see her again for a couple of weeks and I don't want to wait too long and miss my chance. Would it be weird to send her a friend request?
