First, welcome to the forum!!
At my campus, we are loved by the frats, and the sororities,well, are getting used to us. It was a long fight to get on campus, and they are just begining to get used to the idea that we aren't going anywhere. As we wanted our rush shirts to read, "Sometimes loved, sometimes hated...NEVER ignored."
As far as rivarly, tesion, etc etc...
heh, we're working on that. Actually I'm working on it with a select few of the other sororities. those of us that sit on CPH have these great ideas, and some chapter always vetos it. The only thing that bought the CPH together was to be united againt us being recognized. But that really didn't work...
