Please bro, don’t be discouraged by this kind of response. This is a GREAT community and there is no better source for D series knowledge than here.
Just understand that the guys who are still around have seen and answered a lot of the same questions many times over many years. There have been a lot of members who have dedicated time and energy to document the lessons they’ve learned so it’s a little frustrating when all of this great info gets overlooked because of a lack of searching.
Some of us are more patient than others. Thick skin will serve you well in the beginning of your time here. Stick around, learn what you can, and at least give the impression that you’ve looked around before you ask a basic question
Good luck
