Increase Community Service?

I have been involved with Odyssey of the Mind for five years now. And most of those years, we had an informative Mensa table set up, too.

Many members are dismayed that Mensa, in general, doesn't do more community service. In what  venues would you like to see Mensa members performing community service? What, if anything, should Mensa (either the AMC or local group boards) do to bolster such efforts?
