On the strictly open-source/non-commercial front, there are several major players: * Tikiwiki has an editorial engine for submitting, editing and approving article submissions as well as a workflow project management system. * Twiki can be expanded dramatically with server-side plug-in modules that allow for specific handling of functions like calendars, spreadsheets, RSS, barcodes, and so on. * Zwiki offers a plug-in WYSIWYG HTML editor called Epoz that supports all the major browsers. * Perspective is popular with some large companies and seems to be the wiki many big businesses get their feet wet with first. Each of these wiki distributions has its own pros and cons, but each is a stable and functional package right out of the box. Which one you choose will depend upon your budget, the features that matter to you, and your IT department's ability to implement and maintain it
