Ha! Every board has to have em!
I've ran a few of these about 4 or five years ago and they were extremely insightful.
No doubt! They seem to be beneficial for more than one reason. Aside from the obvious, they help to "refocus" folks. However, as an administrator, I do note, that heavy participation, tends to slow down productivity elsewhere. Not, saying that is a bad thing. Just a noticeable one.
Good luck. With the active membership, it should go over well here.
