Wikipage

In the right circumstances, a wiki can be a very efficient way to gather and distribute information. It can improve collaboration among team members who need to refer to, or work on, the same material. Anyone with the necessary editing rights can add ideas and observations as they occur, often in response to other people's updates.

Because they're online, wikis can make it easier f to cooperate on tasks, share notes and suggestions, and contribute resources. Where several authors are updating the same piece of work, a wiki can aid version control, as it's always clear which version is the most recent.
