On the negative press...unfortunately newspapers (well all media for that matter) thrive on "gossip" stories. It means that more people will read what they write. We stuggle with that a lot at my campus.
As to how to get some positive press...def get everything good you do in a press release. If they still aren't printing it, maybe that is something to bring up with administration and your greek advisors. Their job is to help you succed and part of that comes with recognition.
Boo to your paper for no good articles
But keep at it...and use all your resources to help you get some positive press! Good Luck!
