Hi Criag,
one more suggession (if it is not too tough to implement and other too feel it is correct).

Please allow the Poster of a Thread to Delete his/her Thread. It happens many times that
a) The poster, by mistake, presses the Post Button twice.
b) The poster overlooks some part of the original question and gives an irrelavant answer and later posts another one correcting it.
c) The Poster gets what he/she wants and does not want further discussion on the topic, so he/she decides to end it. Also, here, please change the ICON of cheerfully terminated threads.

Warm Regards,
Harsha.
