Hi, I'm the creator of Roundup (though not the original designer, that was Ka-Ping Yee).
In the true spirit of the web, I've had many web homes. I'm currently residing at http://www.mechanicalcat.net/richard and http://www.zope.org/Members/richard.
I've got a few Python projects in the works: Roundup, PyPI? and Gadfly are the most visible.
