@Frank Apisa,
I seem to remember that you have to go to your preferences (bottom of page) and select enable quote button - in order to be able to lift a post verbatim and then deposit it in reply.
Though I do think you should still be able to do it by cutting and pasting and then clicking on the quote button over the reply box. Or, just say, So and so said...
edit - what it gives a choice on in preferences is Show Quote Button (yes or no)
