Hello Sister Greeks!
Over the past year we have gotten several Sorors to reactivate by inviting them to events. We've had a couple of theme parties, which are family friendly [ie bring your kids and significant others]. Also, we do fundraisers which ladies can participate in to cover a portion of their dues. The other benefit of the fundraisers we've done [which require some sweat equity] is that it gives some of our Sorors who have been on hiatus a chance to meet Sorors who have been inducted during their abscence.
Good Luck!
