Check out Moderator if you’re keen on moderating blog comments, and would prefer to do so without a browser window open. Moderator is a WordPress Plugin and associated desktop app, built using Adobe AIR. The function of the plugin is to allow you to view and moderate comments from your desktop.
With this application you won’t have to go to the moderation page again, as it sits on your desktop and keeps your blog comments clean. Once installed, leave it running and it updates itself throughout the day, where you can approve or deny comments in real time.
Some of Moderator’s features include:
Viewing unmoderated comments,
Dock and system tray notifications of the number of unmoderated comments,
Accept, delete, and spam comments from within the desktop client,
Close application window, or minimize it to the system tray while running,
Shows the Gravatar icons for the user who posted the comment.
You can request more features and bug reports by emailing at email@example.com, but keeping in mind that the tool’s just released earlier this week and is just an early version.
