Hey Lilly, there are two ways to quote from a prior message.

1) You can go to the message you want to quote from, and instead of hitting 'reply', hit 'quote' and it will bring up your text box with the quote already in place.

2) To copy and paste from a message, highlight what you want to quote in that message and hit 'control' and the 'c' key at the same time. That copies it. When you have your text box up that you want to post in, first hit 'control' and the 'v' button at the same time. That pastes what you highlighted into your text box.

Hey, I did it!
I think...
