I'm happy to report that the Pybots project got its first user other than yours truly. Seo Sanghyeon set up a buildslave running on Debian Unstable which is running the docutils unit tests every time a checkin is made into Python trunk or in the 2.5-maint branch.
Marc-Andre Lemburg also offered to run a buildslave for the egenix-mx-base tests, while Manuzhai offered to run a buildslave for the Trac tests. Skip Montanaro also expressed interest in running a buildslave, but he hasn't decided on a project yet.
You can see the current pybots buildslaves here. Expect to see more active buildslaves in the next few days.
Marc-Andre suggested I write a Pybots FAQ and put some info on the Python wiki, so here they are:
