Everything can always be improved and will be glad to hear of any of the web pages or program text that could be made more clear.
Bug reports and fixes are always appreciated.
I do test each release against all the supported distributions. However the installations can sometimes be improved. This is almost always down to the order that packages are installed. If you see something that is an issue, even if you don't know the fix, please bug report it.
If you are a Python wizard, any code reviews will be appreciated. Do however remember that it must work under Python 1.5.2 as well, since that is the version RedHat ships even with their latest distributions.
Some of the Tk stuff is hairy, and could do with an expert eye looking over it.
