We've been thrilled by the recent pick up in blog comments and discussions going on at Green Options: we're glad many of you feel comfortable participating in discussions here. Ninety-nine percent of those comment have been constructive, thoughtful and informed. The other one percent… well, we're making some changes to address spam (which has picked up also) and uncivil behavior.
After deleting a ton of spam yesterday, I asked our developers to turn on moderation for comments submitted by users not registered at GO. This does not mean that you won't be able to add your voice to the discussion without becoming a member; rather, it means that those comments will have to be approved before appearing on the site. The content team will be checking the moderation queue frequently, so it shouldn't be too long before your comment appears.
