I also had noticed and wanted to buy one of your go + keyword names for attractive pricing but i was travelling and by the time i confirmed and made sure everything to finally buy the name, The listing was gone. As an active domainer this is terrible to know that godaddy response (or lack of it) on this. Specially when it is the biggest and most popular registrar. And worst thing is with their prevalence you can't even avoid them. I still hope somehow this ends in positive way for you. Thanks for sharing.
