If I knew then what I know now
Major experimentation with converting this blog to Drupal. I found a TREMENDOUS Perl script that, after I shook out a bug in the trackback conversion, sucked down every post from P6/Green without a burp. I did it with the current site.
Okay, I have to start with an absolutely clean database for it to be truly burp-less. And because of the way I posted and converted other sites (see the title) it will not be straightforward rewriting the old URIs to new, Drupalled ones. I'm still working on that , and a couple of other issues I'm probably making a bigger production than necessary about.
But you can see pretty much what the new site will be capable of now. You can set up a user account and access stuff immediately. If you do, don't get attached. It all gets blown away.
