Hi there Ahmed, Welcome to the DP forum! Your curiosity has brought you to the right place. DP is one of the biggest forum on the internet. I Think you will it here. This is a great place to hang out with people who share the same interest like you, and learn new things about internet marketing, making money on the internet and many other general life issues!
Having been a reader, not often a poster of DP, I can assure you you'll learn a lot from the DP boards. But like all things, take it with a pinch of salt!
