VaultWiki allows your existing forum users to collaborate on creating and managing a site's content pages. VaultWiki is a fully-featured and fully-supported wiki solution for vBulletin and XenForo.
The VaultWiki Team encourages you to join our community of forum administrators and check out VaultWiki for yourself.
We strictly use 3.8 series and have no intention of moving to 4.0 or 5.0. Does your product work with 3 series?
Yes, all of our current releases can be installed on vBulletin 3.8.6. However, your site must also meet the other Minimum Requirements.
