I just visited <URL:http://qa.debian.org/> looking for info on how to report a debian developer that I suspect is missing in action.
Looking at the plan package, I starting to suspect that the maintainer Gopal Narayanan is missing in action. If I remember correctly, the QA team is the group that want these messages, but I am unable to find out how you want it reported. It would be nice if I could simply insert the debian user name in some web form, and that this would make the QA team aware of the problem, and put him on the list of developers to check out and perhaps orphan the packages of if the maintainer fail to surface. Do you have such system? Do you want it? Should I report the problem in a different way?
