My main focus has been pacman development. Pacman 3 is just about to be released, and we'd appreciate any feedback about it that you guys want to provide. Just leave it on my User Talk Page and I'll read and respond to it.
I'm looking to get involved with pacbuild development, an automated building system that will make official packaging a lot easier and hopefully fix outstanding missing dependency issues.
I'm not real involved with this yet, but I intend to help out other people with their packages, make minor bugfixes to close some Flyspray issues, and do what the other developers tell me to do. :P
See the [developers page] for all the contact info you'll need on me and the other developers. You'll also frequently find me on IRC in #archlinux-pacman on freenode.
