Decided to try a "Mumm" myself (though not on a subject I really needed my mind made up on- ... well- maybe that's not true either...) - couldn't quite get it to work until after a suggestion from a helpful supportperson (Blondie). The response to the Mumm itself was gratifying.
(Well, not was- has been; there's still two hours left on it, Eric says, promoting shamelessly, though not so much so as to include the link. It's on my profile page anycase- I'll go look for those on yours, as I can, though I can only answer some questions. I think this is a nice idea.)
