* 8/5/2007 - (update1) minor update to "fix" the display on a reply.
* 8/5/2007 - (update2) fixed the real form submission from completing, thereby removing the annoying "5 chars or less" message
* 8/13/2007 - Fixed a typo that caused an error to pop up in the console

Hi. Let's post on the shack from Opera ! !

I grabbed the POST code from here, I think: http://java.sun.com/developer/technicalArticles/WebServices/restful/code_sample4.html

I made this all in a matter of a couple of hours, and it's my first Greasemonkey script, so sorry if it doesn't work.
