As you know, we recently suffered some problems with spam comments, which caused us to resort to moderating all comments (our blog was even threatened with deletion over this mess). However, I am happy to announce that we have REMOVED the comment moderation option and have restored comments to their default setting. We have recently expanded the "Blog Administrator" powers to several of our regular contributors, which will hopefully provide more able hands to the task of deleting the spam. It just became too much for one person to do.
Hopefully the problem is fixed! Sorry if this caused any problems.
