Hey, thanks for coming. There really isn't a ROOT site for wparmchair.com, but here's some past WPArmchair sites:
Themes and plugins for WPArmchair are on GitHub. Please use and improve. Also check out tagregator which is being used on official WordCamp sites. Go read WPTavern's look at WPArmchair as well.
If you ever need anything done (as in WordPress or BuddyPress coding, not getting rid of a body) then drop me a line.
