Everyone should know what a wiki is by now, but here’s a brief definition for anyone who doesn’t: a wiki is a website that visitors can edit. The word ‘wiki’ is actually a Hawaiian term and means ‘quickly’. A user can browse to a website and make a change quickly, get it?
MediaWiki is popular wiki software written in PHP. Wikipedia uses is (it was in fact originally designed for the Wikipedia project) and here is the logo:

Wikis are ideal for sites that require group editing, and that’s also how WikiStudent got its name. Years ago, before the site used wikis, I used to write about Unisa modules I took, and have a form that users could fill in to submit complementary information if they wanted, which I’d then manually incorporate into the page. Imagine doing that nowadays! Hurray for MediaWiki
