Wikis are websites editable by their visitors and their usage is very common method employed by the FOSS (free open source software) community in order to improve efficiency and collaboration.
If you wish to have first-hand experience using a wiki, from the enduser's and contributor's perspective, go to http://www.c2.com/cgi/wiki?WikiWikiSandbox and click the Edit link at the end of the page or follow this link: http://www.c2.com/cgi/wiki?edit=WikiWikiSandbox
A wiki site works by using specialised wiki software, such as a server-side PHP script, which stores the site's contents in a database, such as MySQL. There is no need for special software on the user's side, since the wiki allows the visitor change the contents of a page by the means of standard HTML forms which every HTML-compliant web browser can handle. Some wikis allow anonymous editors, while others require registration.
Wikis are employed by the open source and free software community, as well as many corporations, to allow more efficient collaboration between their members. It is a great tool when a group of people want to share information.
To find an article, you can search for its title or some words included in its contents. However, many people may prefer browsing, so it is very important for all articles to contain links to related pages (sometimes even uncreated ones, to motivate visitors write more!). Starting browsing from the Main Page and using the links included in each article, you should be able to find the article you are interested to in a reasonable period of time. If not, maybe you can help us to improve the site!
