Hi,
Milos Rancic said that I should announce this on foundation-l, so here it is:
I had written a MediaWiki extension specifically for Wikimedia Incubator. It's now enabled, so users can set their test wiki preference, and there are also recent changes per test wiki. For example, changes in the Kichwa Wikipedia test: < http://incubator.wikimedia.org/wiki/Special:RecentChanges?limit=250&rc-t...
More features will be added later, e.g. a welcome portal for non-existent projects that will hopefully in the future replace the current "wiki does not exist" page.
