I think that their should be some help at the top of the postings area. You could even have it only pop up when is user is below a level. Cuz I am pretty sure most people once they get to level 2 or so know how to do it. Also they could put the <code>
put code here </code> inside of the text area that we have to put data into.
<TEXTAREA WRAP=VIRTUAL NAME="reply" ROWS=10 COLS=60>
<CODE>put code here</CODE>
</TEXTAREA>
