OG Join Role

1. http://drupal.org/project/og_joinrole
3. The OG Join Role module simply adds a "join organic groups" permission to the Organic Groups module. A use case for this would be if you have a site where only members of a certain role are allowed to join an organic group.
   The module is written in an all-or-nothing sort of way - either certain roles can join any and all groups or they can join no groups. It will not work on a per-group basis.
   In addition to granting/denying permission to join a group, the module also modifies any text and/or links to join a group unless the user has the proper role. For example, the module removes any "og/subscribe" links on the page and replaces them with "nicer" text that you define in the admin settings.
