domain TestPilot.com

[Brandaisy]

Hi
I've bought a lot of domains over the years but not tried selling many. So I thought i'd start to auction some off. The one with the most traction if TestPilot.com which has 5 days to go and is at $5000 on GoDaddy Auctions.
Where can I advertise it to get more bidders?
Any help would be great.

Thanks
K
