Bug Reporting
I try and do a lot of bug reporting, and collate it here. I think bug reporting is one of the best ways people can pay for free software.
Debian
I submit bugs via a particular email address, here is a list of my open bugs. I have, however, used a number of other addresses in the past, and so archived bugs are in a number of places (1, 2, 3).
KDE/Konqueror
I have put up a collection of bug reports and test cases for konqueror bugs (mostly stylesheet ones) at http://toast.debian.net/~jmtd/konqueror/.
Please note that these are now fixed in Debian/Unstable.
Sourceforge
Minor fixes for strace; beep-media-player.
Patches
Patches submitted to fix bugs are all in /code/bugs/patches/.
