Beware, there is an "Education cooperative" which they call just "the coop". m:Wikimedia_Foundation_Report,_May_2014#Wikipedia_Education_Program for instance.

Thanks for pointing this out, Nemo. I think this is not a big issue, though, as long as we make clear we are "the wiki coop" :)
Ok. They are "wiki" too AFAICS.
We changed our proposed name to MediaWiki Cooperation. Not cooperative. Let the shortcuts be made by others ;)
