The history feature in a wiki is useful in many ways:
Version control
- the wiki maintains almost an unlimited number of versions.
- you can view each version in (v)iew mode or in (s)ource mode.
- (r)ollback creates a new current version from any old version.
Accountability
- the login and/or IP address from each editor is visible in the history page.
Comparing versions
- choose any one version from column A and compare it with any version from column B
