Although most of the time I'm using it with fairly savy computerists, I've also set up some discussion boards with UseMod wiki for some academic student/faculty committees. Some of the committee members didn't like the wiki, but I think those folks would have balked at anything online. Many of the people on the committes found it a useful tool.

I have looked at the Everything engine a bit, but so far the overhead in setting up a sql engine for it and mastering its customization world has been a bit too much.
