how it works
This script works in internet explorer, netscape and firefox. Any other platforms haven’t been tested. That’s kinda up to you.
If you want to force a textarea over a textfield (for example to edit a piece of HTML) use class="editText" offsetHeight="10”.
If you want to PUSH an ID to your script I use: id="edit_userID_$userID". In your update script, strip the text, and keep the $userID. Et voila.
