Hi,
People interested in projects similar to OpenGuides might be interested to see http://wiki.ournottingham.net/, whose creator apparently felt that http://nottingham.openguides.org/ didn't quite fulfill Nottingham's collaborative-city-guide needs[1].
It uses MediaWiki, which is cool in some ways (discussion tabs!) but lacks features I for one consider important in OpenGuides (structured metadata, x-y coordinates) and apparently the content it released under the GFDL, though this information is hard to find without a spot of digging.
While we're on the subject, does anyone know if the GFDL and CC by-sa 2.0 licence are "compatible" in either direction? That is to say, can content from either of these guides be easily included in the other? My rough understanding of the licences suggests not, but IANAL.
Cheers, James
