You need to manually add quote coding through the post to chop it up into bits for reply purposes. When you get to the end of each piece you want to quote put (/QUOTE) but using square brackets instead of round ones. Then press return to start a new line and type your reply.
When you want to go back to quoting from the text you're replying to, press return again and then put (QUOTE) but using square brackets instead of round ones.
Example:
-----------------------------------------------------------
(QUOTE=Arthur Antelope) Yadda yadda yadda (/QUOTE)
Yadda to you too.
(QUOTE) More yadda.(/QUOTE)
And the same to you doubled on Tuesdays.
(QUOTE) But I said yadda yadda yadda!(/QUOTE)
Yes, I heard you the first time.
-------------------------------------------------------------------
with square brackets instead of round brackets will look like this:
-------------------------------------------------------------------
And the same to you doubled on Tuesdays.
Yes, I heard you the first time.
