Brian, once you get comfortable with it, you'll wonder how you ever got along without it. I've had my 18" Echo for about 2 1/2 years and wouldn't be without out. You've gotten lots of advice, just never lose a healthy respect for what it is and what it can do.
Some of my own rules for me are:
Always start it on the ground, with a foot on the handle and the chain brake on.
The only time the chain brake is off is when it is actually cutting.
Don't cut with the tip and only cut when your stance and footing are secure.
Never cut when you're fatigued. When you start getting a little tired and/or sore, then it's time to stop. The "just one more cut (log)" rule applies to chainsawing too.
If you question wether a cut is safe or not, then it probably isn't. Common sense is a wonderful safety feature that you should never be without.
