To help Blogger users better access, moderate, and manage their comments, Google has implemented a Blogger comment moderation management tool, which integrates an automated spam filter. Release of this new feature has been throttled to blogs, and is subject to Google's release schedule.
More importantly, this new Feature coincides with Bloggers 11th Year Birthday!
Having been an early recipient of this new feature, I wish to thank both Google and Blogger of adding such an important tool and giving it to us!
Happy Birthday Blogger! (and thanks again)
