Add-on [Paid] XenForo ↔ Craft CMS user account bridge

I am in need of a user account bridge between XenForo and Craft (a PHP-based CMS that uses the Yii framework and has native support for plugins, as well as - with the Users package, which I own - profile fields, groups, permissions, and so on).

  • User accounts, groups, permissions, etc. are synchronised between the XenForo and Craft databases.
  • Craft acts as the "controller" (registrations, validation emails, authentication, profile fields, permissions, etc. are handled through Craft).
All in all, something a bit similar to the xF ↔ MediaWiki bridge. Shoot me a PM if you're interested in tackling this.
