I enjoy helping and teaching others where I can, but I wouldn't class myself as a professional (yet), the majority of the questions I become involved with are just a good way to learn more about the subject myself. I primarily joined this site as a means to ask my own questions and get help with subjects I am currently learning, I do not compete for points, although its nice to know I have provided a working solution, or even better, taught somebody something.
