This listing actually comes from a database I’ve put together myself. The database serves two purposes: to put together the web pages (in which case full typographical control is desireable) and to create the input file for my sig file (in which case the lowest common denominator is desired).
Rather than come up with something elaborate that translates stuff back and forth, for the moment you’ll have to put up with italicized items in the quotation text showing up as *starred*, and _underscored_, and other Net-like typographical conventions. If you don’t like it … sorry. Maybe I’ll do something fancier one of these days.
UPDATE (24 Jul 07): One of these days is now, since, working through MT, I can actually do rich text formatting and the like in HTML. Yay. I did some mass conversions of quotions to turn the _s and *s into italics — in some cases that messed up, so if you spot a problem, please let me know.
