I understand how hard it can be to create a sense of community among the NPC chapters. One thing that our Panhel is trying is that we have chosen our own philanthropy - our university's R.A.P.E. center. We chose it because it benefits all women on campus, not necessarily just greeks. We are organizing a 5K walk/run to benefit the R.A.P.E. center...this way all sororities can participate in a philanthropy for a good cause that benefits them AND there is NO competition involved. Almost all the philanthropies sororities are involved in on campus are put on by fraternities and they become huge competitions between houses - which of course turns into problems between these houses. We're also trying to get sisters from every chapter involved in community service and other events together. Also, try your best to keep an open line of communication...it's much better for girls to bitch to your face then to have them get together and bitch about how much they hate Panhel behind your back. Hope this helps and good luck!
