AuctionSyndicate.com is a site that is in development here at HATCHideas.com that will allow users to submit links to auction sites, be it their own, or a link they find fascinating. It is in alpha testing right now, and was public for a short time but had issues that required it to be taken down. It will be up by the end of the first quarter, 2009.
If you are interested in working on the project, feel free to contact me here or otherwise.
