Ok so that title definitely could have been worded better. It's 1am right now.

Anyway, cold approaching is when you introduce yourself to a girl you don't know and she doesn't know you. But what is it when you are building your reputation/friendship "status", if I may, and trying to attract people within your group?

Also where can I find more information on improving this aspect?

Thanks in advance and again sorry for shitty question title!
