So, I had covered this topic in a blog article years ago, but I really thought that it would be fun to revisit it. For those just getting into the hobby, maybe talking about these trouble spots can help you to avoid some grief. As for the veterans, I think many of us forget how confusing aspects of the hobby could be when we first got into it. Perhaps talking about some of the pitfalls will help us to be more reasonable the next time we have to answer a newbie's question.
