I'm trying to stop the editing of Group Titles (Content Types that are set as Groups) by users. With Drupal (v7.21) I've added Organic Groups (7.x-2.1) and set it so that the Group manager does not have full permissions. Instead I've created a Role for them called 'owner' and give them the ability to edit the group but not administer the group. I want them to be able to change the Group Body but not the Title. I have the Organic groups field access module installed and that lets me stop them editing fields like the Body but it doesn't allow me to stop them editing the Title. Does anyone know if there is a way to do this?
