4 Not all wikis are Wikimedia
The word “wiki” refers to a website built using collaborative editing software. Projects with no past or existing affiliation with Wikipedia or the Wikimedia Foundation, such as Wikileaks and wikiHow, also use the term. Although these sites also use "wiki" in their name, they have nothing to do with Wikimedia.
200,000+
editors contribute to Wikimedia projects every month
