If everything worked out ok this post marks two things:
1) Post number 992 on this blog
2) The debut of a new comment management system, called JS-Kit.
Whilst I was converting my blog to the new format for comments, JS-Kit kindly told me that it had converted 767 comments
And, if it really worked, you should see several new options if you want to leave a comment - including support for avatars/user profiles and images and facebook connect logon (as well as several other logons).
