I'm sure many of you know this. I've never bothered to look at the buttons above me, so I wanted to share my trick. If it starts making you type in a quote box, stop typing and click the button that says "show source"
Then you will see something similar to below. Find the last end blockquote line (1-underlined) and start typing after it (2-"Yes."), then press the show source button again (3-circled).
Then you should see your text outside of the quote box.
