Cheeze and crackers. Talk about taking the long way around. Shippensburg's Greek site is totally outdated and rush isn't mentioned anywhere in the calendar. I finally found an answer on Alpha Phi's national website!! (big snaps to Alpha Phi)
They have formal rush dates listed for all their chapters and Ship's is February 2004. That would mean what is going on right now is informal rush or COB. So it's OK for the AOPi's to call you.
Some chapters call the women who signed up and some don't - it's purely a matter of personal preference.
