You are a beautiful, beautiful man! Thank you! Now WordPress completely beats out MovableType. (The MT subscription model was the only thing I’ve missed.)
Two issues, though. After I got it running on my blog, I set to putting it up on my friend’s blog, which I host in a subdirectory. The “go back to blog” link defaulted to the home directory (my blog) and not to his. I went through and manually changed the six or eight places in mailer.php, so it was no problem. But that might be trouble for others.
Second, I noticed a comment about the .dat being insecure and needing to be changed to .dat.php. Is this so?
