I've installed a new version of WordPress – and Project Pamela's InfoCard plugin (more later) – and I'm using it to run my blog as of NOW. If you see anomolies, let me know.
The good news is Project Pamela's InfoCard plugin is really slick. It worked right out of the box.
It doesn't require WordPress 2.1.2, but I wanted to get to the latest revision.
The bad news is that if you currently log in with an InfoCard you will have to respond to an email sent by the system in order to be switched over to the new way of doing things at my end. Pretty painless though.
ISSUE: Password registration is still not enabled while I figure out exactly how it works
