Since your able to make it look like a quote came from anybody, and make it say anything, you can do this to display literally anything. The way this game works is simple: when you put someone's name in the quote, XenForo makes the top of the quote box say: "User said this". All you need to do is add the words "might have" after the persons name to make it say "User might have said this". Don't use something that you know for sure they said, but something that they might have said based on their personality on these forums. For example, instead of which is something that @MCPEPIG really did say in one of his profile posts, you could do Ready? Let's start!
