Hello, I have been following this forum for a long time without registering and I have finally decided to join. I would like to give useful feedback and get help if I ever don't understand something...I hope I will not be too heavy with my newbie questions 
In fact, giving me instructions on where to find the information will suffice so if you could give me now some useful places to look, for a beginner like me, I will know where to start? 
it's really a great resource for all kind of applications!
