So you have choosen to try this wiki. TipiWiki is simple, featureless and small. There are no users, no passwords, no version, no backups, no diffs and no database. TipiWiki is created after KISS. Keep It Simple, Stupid!
There will be no extended version with such features. If you need them, there are more powerful wikis out there, even some based on TipiWiki.
