This is a wiki. Wikis are web sites whose content can be directly edited by various people: in some cases, anybody can edit, in other cases, only a limited number of people can edit. You can also edit things that other people have written, either to correct erroneous information or add more detail.
The basic unit of a wiki is the page. A wiki page can be treated as many things:
- a regular web page
- a folder or container to organize other pages
- a place to store attached documents
- a web application that can reference things outside itself
A wiki page can be any of these things, or all of them at once.
A wiki's success depends on people's willingness to share their knowledge, and that most people know a little bit, but few know everything about a given subject. If we pool the knowledge, we make it available for everyone.
