Ah, another one has fallen victim to the fateful bug ....!
Welcome Mark. I'm glad you've found us.
Don't allow the fact that there is so much to learn, overwhelm you. It can seem daunting. But take it one step (or one skill, or one area of knowledge) at a a time. And then you do begin to feel all the bits starting to slot into place together. But of you push it too hard you just get more and more frustrated.
But this is certainly a forum where you will get all the help you want. Our focus is on learning and supporting colleagues. So, please do join in.
