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.
VaultWiki is a full wiki. There are plenty of wiki-related features and new features are being added all the time. VaultWiki uses your existing XenForo style. If you have a custom style, you might need to change only 1 or 2 style properties. For basic usage, there should be no need for you to learn any new coding. You write wiki pages using your existing XenForo editor and BB-Codes.
