Hey guys! I am going to be a freshman in college this fall, and at this time of the year it seems that many girls are joining "University Class of 2015" facebook groups. I made a few posts on the wall of the group and a few HBs added me to their friends lists (IOI, correct?), but I have no idea how to proceed from there.

How do I build comfort so that I am immediately on good terms with them once we all arrive on campus? I am a little bit worried about getting friendzoned through facebook and I think that I've read somewhere that being online in facebook chat is seen as something of lesser value.
