You sound like me; I lurked for a while too. (But there was also a good period where I didn't touch the APK website.) I also dabbled with parkour a bit, for several months (like, nine or something, actually. I ) That's why I have no idea what to say if anyone asks how long I've been training. I didn't start real training until just before the weather got cold, which didn't really turn out great cuz I can't train now (freezing rain sucks.)
So anyway, my advice to you is to get comfortable with your body and moving your body, and then move on to technique practice.
