I deactivated trackbacks for this blog, because policing the pings for spam became more of a chore than I want to deal with. Apologies to anyone who tried unsuccessfully to leave trackbacks. I can only suggest that you leave manual trackbacks in the form of comments.
I am trying to avoid upgrading this blog to MT 3. As soon as I can figure out an easy way to port our templates to WordPress I will do it. Suggestions on this topic are more than welcome.
