Confluence, at its base, was built on the principle of a Wiki.
A Wiki or wiki (pronounced "wicky" or "weekee", see pronunciation section below) is a website (or other hypertext document collection) that allows a user to add content, as on an Internet forum, but also allows that content to be edited by any other user. (from wikipedia)
Confluence has many features which extend beyond average wikis. Please find a few of these in the list below. You may also find a growing list at the Confluence Documentation homepage .
