Old(er) hobb(y/ies): redstoning (I helped rig an entire colloseum once, many versions ago with TheWhiteDragon, whom I also helped with his server) New(er) hobb(y/ies): building, helping new servers take a foothold...
I enjoy helping others out with their new servers, mostly because many new servers need someone who knows about setting things up, which means I can take charge. I do a range of things from gathering art, making/setting up websites, providing an idea that would work for that server, permissions, et cetera...
I also make skins from time to time if I get very bored. Lack of passion/interest is one of my excuses for my skin quality being very low. :)
