RE: Just wanted to say Hello!
Welcome to the hobby, As you learn you may, scratch that, will become over whelmed. This is a great hobby and is very gratifying. I hope you have fun, and to add to what Ken said, Your cousin is still learning and you may pick up any bad habbits or maybe miss informed.
Have Fun, Dave Trimmer
P.s. no one is finished learning, and there is always something else to learn.
