Asking board members to call past donors and thank them for their support is often a way to rekindle the interest of people who have not made a donation in a while said experts who participated in The Chronicle’s latest online discussion.

Among the other suggestions:

• Offer past members of a giving club who donate, say, $1,000 a year a one-time offer to reinstate their membership with a contribution of $700.

• Use anniversaries and other special occasions as a chance to give past donors new options to give or get involved in the group’s mission. For example, one charity started a contest to see who could come up with the best redesign of its logo.
