Ok, so I met this cute girl at a club this past Sunday. She was cool, I was cool, got her number. Anyway, she texts me back at like 3 am saying she saved my number, and I talk to her a bit the next day, and make plans to hang out with her this Sunday (very tentative plans - all I've got was, "Do you wanna do this?" and her response was "Sure, sounds good").

How should I do follow-up for the rest of the week? Obviously just texting her Saturday or Sunday with, "We still on?" will result in failure, so how frequently should I be contacting her, and what should I be saying when I do? Random questions? Random funny things? Once every day or two?

Typically I say two funny things over time, and then ask a personal question. She's seemed down so far. She's very sarcastic. My introduction of, "I'm sortof a dick" worked well on her, and the fact that I knew where her home country is (I am an American, and she is originally from Bosnia).
