Since SixApart fixed their pricing we were able to afford Movable Type 3.0! And now it has been installed. I have enabled the TypeKey comment authentication system, but it is not exclusive -- meaning you can still post a comment without registering at TypeKey. The only drawback is that all non TypeKey posts will have to be approved by me before you see them on the site.
This should defiantly help curb comment spam, which has plagued this blog for some time.
If you notice any issues since this upgrade, please let me know.
