What is "userpress"

UserPress is a wiki plugin for WordPress. It is one of the few WordPress wiki plugins in active development.

The software is designed to be used from a web site's frontend (as opposed to the wp-admin backend).

UserPress does not currently support any kind of wiki markup. However, it may be possible to add such functionality through a third-party plugin.

Additional functionality such as automated backups and page caching can also be performed using existing WordPress plugins.
