Google+ Community has got new indicators "owners" and "moderators", which will act as distinguishing factors between users. It is considered to be an extremely helpful revision for communities. The respect roles of community members will appear next to their names.
While announcing the revision, Brian Glick also said that new labels will be applicable to both; posts and comments. He also revealed that Owner label is also introduced in the update.
Brian also said that they tried to add a star to the profile photos of community staff for their comments and posts, but it wasn't very much noticeable. We hope that there will be plenty of new features arriving soon for Communities.Google Communities Get Moderator/Owner Labels!,
