The boards and the main site have a ton of resources on the topics of not being a creeper and how to talk to girls.
You'll have to do the digging yourself, but I'll give you some keywords to get you started. For the board posts, just dig through the different sections. The reports section will give you some real-life examples and dialogues that worked. For the main site articles, go to google and type in "girlschase KEYWORD" where KEYWORD is one of the stuff below:
Social calibration
Deep diving
Conversationalist
How not be creepy
Those 4 are the only ones I can think of right now. You should be able to article hop off of those and get a ton of enlightenment.
Also,
read this. I feel like that's also a necessary read since you're a fellow college student.
Good luck.
