Or coöp if you want to be fancy.

It's generally inconsistent. The first sentence is written, "A co-op is an economic system built on the simple idea that coordinating the economic activity..."

Co-op is correct here, but not in the title (Coop). Probably personal taste, but I'd also like to see hyphentation for "co-ordinating", "co-operate" and "co-ordinator" as well.

Then I noticed the em-dashes, so perhaps I'm reading the machine's work anyway.
