This is what you do dear, when you click on "reply" and get to the reply page, scroll down and you'll see the posts of at least 15 persons before you.
Above each person's post to the right, is an "insert post" underlined, click on it and you'll be telling a new story

Now if you want to quote someone that made a comment ages ago, or the person's post has been followed by lots of people making it not appear on the page, simply "copy and paste", then above our smileys there is a button with a "light yellow", would i say piece of paper in the middle
Highlight the post you pasted, then click on the yellow button, it will come out as a quote, but not with time, date and name as it would have if you used the first method, so to specify whom you're talking to, just write something like "quote from so so person" above
Hope i made some sense, Holla back if you're still wondering

I'm at ya service!!!
