It's great to see so many helpful people
I hope that the people asking don't get discouraged or intimidated by the those who reply with snarky and sarcastic attitudes. Ignore those, don't pay them any mind! As you can see, there are plenty of nice people here who are very patient and kind, and who remember what it was like to learn new concepts with an overwhelming amount of new information.
We were all there once: new and empty, ready and eager to accept new knowledge. An important part of being a teacher/helper is to
never forget what that feels like! In fact, there is always more for everyone to learn!
