So I was going to ask if anyone knew how to make the text area editable in Web Forms.

Then I did some googling and came across this dead simple JavaScript library. All you need to do is to add:

<script src="http://js.nicedit.com/nicEdit-latest.js" type="text/javascript"></script>
<script type="text/javascript">bkLib.onDomLoaded(nicEditors.allTextAreas);</script>

into your .html (in my case .php page).

From http://nicedit.com/

Thanks for that post. Gotta love scripts.
