I think this is how you do it, I copied from J.R.'s posts (she quotes a lot) and I can tell they are clearly quotes.
Hope this helps.
"you can use the http:// code to referece the post. hope that helps."
I'm sorry my question wasn't clear. Is there a way to paste what you wrote "you can use the http:// code to referece the post. hope that helps." in a way that makes it clear that I'm quoting you?
I think I've seen it done with a blue line along the left side of the quote. Does anyone know if it's possible to do that on trulia?
