I've joined a group, but seem to have fewer rights than in other groups

Groups have extended privacy settings. The owner of a group can decide him/herself if members can post comments, whether they should be moderated first, if members can upload/edit pictures/videos and if everyone is allowed to join the group or not. The owner of a group can also appoint co-owners and moderators to help him/her manage the group. Create a group of your own to discover all possibilities!
