I found a threaded message board named discussionthat looks very promising. It is written in PHP and, aside from HTML output of the message board, all the code is in a PHP class. This means, if it is written well (which, at first glance, it appears to be), I can easily integrate threaded discussion functionality into revjim.net. The biggest advantage of this is that, comments will work a lot nicer. Since it is in a class, I should be able to easily attach it to each post on revjim.net. It will allow user information to be preserved, threaded comments, and email notification of new replies.
I love well written, modular code. If I get this working well, I’ll offer a how-to, and downloadable code for integrating this functionality into your own Movable Type installation.
side note: Why does Movable Type require so much damn Javascript to operate correctly? And why is it so slow?
