Wiki
From OLSEncyclopedia
A Wiki is a type of website that makes collaboration on a project by multiple contributors very easy. Due to the ease of editing a page, this is often a point of contention as random people can easily come in and vandalize a page. However, most wiki software includes a page that shows the recent changes on the wiki and the ability to watch an article and be notified when it is changed, which makes finding and reverting vandalism very simple.
Wiki syntax
Wikis typically have their own markup syntax that is wildly different from HTML. This syntax is simpler and cuts down tremendously on page creation and editing time.
For instance, in HTML, to link to another page on your website:
<a href="http://wiki.outlawstar.net/index.php/Main_Page">Back to Main Page</a>
Whereas, in wiki markup, the same thing:
[[Main Page|Back to Main Page]]
Wikis also typically support templates, which make it easy to re-use common wiki syntax between pages. This is used on Wikipedia for info boxes on various things like television shows, actors, video games, and much much more.
