Well, I've tossed out another itty-bitty WPF application, it's located here: Jedi Council PM List. And while my other application (eComic) is very specific in its user-base, this one makes eComic look like MS Word in its potential user-base.
It's basically designed to be used by a subset of the users of the Jedi Council forums (http://boards.theforce.net) to allow said users send their private messages as a PM List.
Of most interest is the fact that it is web site automation via WATIN. WATIN of course is designed for automated web testing, and is something that's needed for a couple of projects that are in the wings for me.
