I gave it a pass because it was new, and then last year it vanished. It's has since reappeared and there is some content on it, but little I haven't seen elsewhere. I mention it because this is the kind of resource we need and I'd like to stoke some interest in it.
EmergingUU.org is sponsored by the Central Midwest District. New congregation development is largely in the hands of the districts now, and the midwestern districts seem to do a bit better job of it than the rest. Or at least until recently when the taps all but dried up. It makes me wonder who's still in the emerging hopper; I feel a little project coming on.
