I left this group about a year ago and have just recently come back. I did this after frustration over some of the same reasons you mentioned. The funny thing is, I know just enough to be a newbe at this. I was seeing the same type post everyday and some " so called expert " acting like a idiot. When you first get into this hobby, you dont know enough to even ask a good question. As time goes on, you get bored hearing the same thing everyday. I agree with everything you said 1000% ( except puntuation ) I'm the worlds worst. My only suggestion is just remember we are all here for different reasons. To learn, to teach, or just to have fun. Its a great hobby and thanks to all who have helped me.
