Use the Wiki
From Reproductive Health Leaders Network
A Wiki (from the Hawaiian word meaning "quick") is a web site that anybody can edit from his or her web browser using a simple set of text formatting rules. You can think of them as a giant, blank notebook that several people can use simultaneously. A good introduction to Wikis is at the original Wiki.
Wikis are widely used as group authoring tools and also as forums for online communities. Perhaps the best known Wiki is Wikipedia, an online encyclopedia with thousands of entries in multiple languages. Anyone can contribute to it -- and thousands have -- by simply clicking the "Edit" button on one's browser. More people access Wikipedia than the online edition of the venerable Encyclopedia Brittanica.
We use a Wiki hosted by MediaWiki.
The simplicity of Wikis make them powerful, but also disorienting, even intimidating. Where do you write down your thoughts? Is it okay to edit or even remove other people's text?
There is no single answer to any of these questions. The rule of thumb is, there's no wrong way to use a Wiki. Don't be afraid to play and experiment! If there's a better way to say something or a better place to put it, you or somebody else can easily change it later. Social norms will evolve with use and time.
