I’m disabling the comment moderation feature. This means first-time commenters should be able leave a comment and it will appear instantly. I had been policing the comments because of a recent spam outbreak, but I think it’s under control now. So, no more waiting a few hours for me to check my email and see that you’ve left a comment!
Also, with the upgrade to WordPress 2.5, we now support gravatars in the comments. See their website for more details on how to have the same avatar display on all gravatar enabled sites.
