K2 User Plugin
It assigns the users automatically to a K2 group. If you use other extension for users handling (like JomSocial, VirtueMart and similar), the users do not have any K2 user group assigned. And then this small modification solves that issue. The user is automatically assigned to the registered users group in K2 (or other if you set it in the plugin parameters). This plugin does the trick for newly registered users only.
