I love myself and I love my life! I just hacked the software for my beloved board to add a new component, "legal.cgi" (which displays our legal and copyright rules), with a proper template and everything. Er, it sounds trivial, but you'll have to take my word that it was trickier than I make it seem.
The main advantage is that it's not quite a flat .html file any more – the script will insert the dynamic page top and bottom code without my having to change the file manually. AND AND AND, the legal template is listed and editable in the Appearance Manager list in the admin program without my having to do anything special! I love Discus. It's organised like it ought to be.
Coding things and making them work gives me a sense of power. And cobbling things together with no knowledge of Perl or of Discus's architecture, and making them work, makes me a very very happy gender-confused individual.
By way of celebration, I've just hacked this WordPress theme to make the date and time display properly.
