Just registered, thought I'd say hey.
I'm not really 'new' to cycling, as I biked quite a lot before I got my driver's license... lapsed through most of my later teens and early 20s, returned to it a little over a year ago. (I'm 29 now.)
Only recently have I really started to take an interest in the maintenance/mechanics of bikes. I traded in my old Magna piece-of-crap from Target for a mid-80s Bianchi roadbike. Modded it into a 7 speed with some home-made bullhorn bars, and it's now my daily commuter vehicle.
I also just got a Giant MTB which I plan to fix up into my urban warrior bike, as the streets of San Francisco are rather unforgiving on my Bianchi.
