Congrats on your offer! Though $200 is a nice [and essentially] fair offer this early in the dot CO rebrand, for better profits you probably should have just countered in the mid-upper $xxx range, and bargained down to your bottom line. However, perhaps there will be some interest in the auction to drive the price a bit. You may want to consider contacting all possible interested parties, end-users, friends, etc; letting them know it is up for auction. You will want to draw as much interest to the name as possible.
:imho:
Congratulations on your offer once again, and best of luck with the sale.
