"A fall gift is a 'green gift' as the College will remove you from the normal schedule of appeals until fall 2009, saving resources that can be better spent on education (rather than postage and printing)."
That's almost annoyingly clever. What donor doesn't get irritated when one gift just becomes a prelude to a flood of letters asking for more, and worry about the wasted resources? I have a feeling we'll be seeing this on many fundraising letters in the future. Meanwhile, I just might make that gift.
