Why is this thread important? I'll tell you why. Because a beginner asked it. That's why. The old saying "The only dumb question is the one that's not asked" is very true, especially here. The beginner's forum here on RCU is here to answer questions that beginners may have as they get started in the hobby. One of the things that we do here is to try to never make the person feel like their question was silly or stupid, because it's not. Another thing that we try to do here is to not tell people to go "search" the thread for the answer because it has been asked before. This turns people off in a hurry, trust me. Instead the regulars here in this thread will answer the same question with the answer, no matter how many times they have answered the same question in the past. This is just part of what we do here to try and help people get started in this hobby. We try to make people feel comfortable and find the answer to the questions they may have. If you feel like this is a silly question then that of course is your right, but please don't try to make other feel dumb because they asked the question. If it's a silly question for you then this may not be the right thread for you to "hang out" in.

Oh, and for the actual question at hand. It is important because almost every student I have taught in the past 8 or 9 years has asked the same exact question. My answer? I teach both, use what you feel comfortable with.
