One way we increased alumni involvement was to involve them with new members. Sometimes alums feel they can have more of an impact if they catch the pledges right away when they join the house.
We started a "Slightly Older Sis" program, where we assigned one alumni member to a pledge, and they would exchange letters, cards, gifts on holidays, whatever was appropriate. It got the alumni directly involved with the members and it kept the pledges interested because they got all the "good stories" from "back in the day".
