Trying to get in contact

Hey VIP, it's me, one of the guys from last night.  I was post 123 in the MM thread, and I'll copy my post here for the lazy:
[I have an issue of my own. I take a walk after classes with this one girl everyday, just chatting about how classes went, daily things.  She said that she can't wait to see me after break, but I don't have her number.

How can I go about contacting her?  I need to strike while the iron is hot, and I feel that she is someone great.

I can't go about it through facebook , but we do have mutual friends.]

I ended up getting a phone, so I'll go about getting her number.  In other news, I mentioned her not having a facebook to a friend trying to set me up with her.  He told me I have just been spelling her last name wrong.  Before I send her a request, I need to change my year-old profile picture.
Should I:
[1] Take a douchey self shot
[2] Get a friend to take a spontaneous one or something along that line
[3] Take a picture of me snowboarding on the 26th, and just try to call in the meanwhile.

Thanks for reading, I'll try and check back fairly often with VIP QUALITY.

Ask her for her number the next time you walk home with her. You should have before now really, if she's looking forward to talking with you near daily then she really likes you.
