If you want to try using JavaScript, this might give you an idea about how to implement it. This code will strip out any quotes that came from another post (as opposed to regular text wrapped in quote tags), and it will also leave any quotes that are inside code tags as-is. Whatever is stripped out is replaced with a brief message. You'll still have to wrap the resultant text in quote tags with references to the original post.
. Copy the code into the left textarea, and click the button. Then on the right-hand side, paste the message into the top textarea. Ah, you can figure it out.
