If you are still interested, we will create a small example addon. I will start from the very beginning with some basic explanations and from then on we will move forward into Lua. I want to provide such an introduction to those highly motivated players with their own ideas for tons of addons. There are several websites which document the ingame API, but most of the things you still have to find out for yourself. What held me back a couple of times was the relatively high hurdle on starting because it is not very well-documented. Being into programming since 2001 and into WoW since 2006 it was only a question of time that I started looking into WoW addon programming.
