In order to improve the management of all communities on Orkut, Google today launched "Admin History" to every community owner and moderator.
Moderators can now view the history of all important administrative actions taken in the community -- both his and those of other moderators -- in the last six months, including:
- members removed
- join requests that were declined
- users banned or un-banned
- co-owners and moderators added or removed
- topics, replies or polls deleted by a moderator
