Advanced Comments Moderation makes managing your WordPress blog’s comments far easier.
It equips you with a powerful set of options for making the moderation of comments via WordPress’ Comments screen far easier:
With these settings (which can be found in Settings > Discussion in your sidebar) activated, you will only see comments that require a response on your Comments screen. All others are either automatically removed or can be manually removed.
With Advanced Comments Moderation you can get to “Inbox Zero” in the WordPress Comments screen!
