Hi Chris, re "Features that enable groups to communicate", I recently posted to Wikia central with a similar idea, but no takers as yet.
My second posting gives a bit more detail of the kind of thing I'd been thinking (if you can read all that!) In summary if 'one big wiki' users could be tempted to use something like ning, or one of the suggested alternatives or something like WiserEarth wouldn't we stand a much better chance of getting better connected? Doesn't seem too be much mention of WiserEarth here (?) I'd be interested in any thoughts you might have about WE and the other alternatives mentioned Philralph 16:34, 20 May 2009 (UTC)
