I've changed security on the blog to use the SCode MT Plugin. Comments don't require email addresses anymore and are instantly added if you provide the appropriate CAPTCHA security code. I couldn't get the GD libraries setup on my windows machine for testing, thankfully all required modules were already on my host's Linux server. Hopefully that'll eliminate spam from the comments, but I also need to install CCode/TCode reduce trackback spam. I might completely move over to CCode so that I can cross-platform develop more easily.
And it works!
