@dalehileman,
Go to the "New Posts" screen. When you are there, scroll all the way to the bottom and you will find a bunch of options, one of which is "Preferences". I don't recall the exact wording of the choice you need, but it will probably be obvious.
Once you are set up right, you should have a Quote option and a Reply button at the top of every post you might answer. Also, when you select either, your reply box will have the standard editing options at the top of your reply box.
Actually, I don't know why these choices are not the default option. I don't get to make decisions.
