What is a wiki?

Essentially a wiki is a set of web pages using easy-to-learn mark-up, that can be edited by anyone with the correct permissions. Currently this site does not use permissions, and so anyone can edit it. For more info, you might want to look at:

Getting Started faqs [http://c2.com/cgi/wiki?WikiGettingStartedFaq] on the original WikiWikiWeb [http://c2.com/cgi/wiki?WikiWikiWeb]
http://www.wiki.org/
the Wiki [http://en.wikipedia.org/wiki/Wiki] entry in the Wikipedia [http://www.wikipedia.org/] online encyclopaedia (based on a wiki).

There are now different wiki systems around, just like there are different makes of car, that basically do the same thing. This wiki uses PmWiki [http://www.pmwiki.org/wiki].

PMWiki

Here's the link to the PMWiki homepage [http://www.pmwiki.org/]. To learn about how the mark-up works for editing wiki content, see the Documentation Index [http://www.pmwiki.org/wiki/PmWiki/DocumentationIndex]. Mark-ups that are possible include:

Heading 1

Heading 2

Heading 3

Other Wikis

One of the best know projects showing what wikis can do is the Wikipedia Project [http://www.wikipedia.org/], an online encyclopaedia that users can contribute to, which is run by The Wikimedia Foundation, a non-profit foundation. They also run:

Wiktionary [http://en.wiktionary.org/wiki/Main_Page] (a free dictionary)
Wikisource [http://wikisource.org/wiki/Main_Page] (a collection of public domain or FDL-licensed texts)
Wikibooks [http://en.wikibooks.org/wiki/Wikibooks_portal] (free textbooks for schools and universities)
Wikiquote [http://en.wikiquote.org/wiki/Main_Page] (a collection of notable quotations).
