That is awesome, good luck. I would prefer it if you renamed it, since it is not actually an extension of my site, but an all new site on an already established woot stalker site. That is just an ethical and courtesy request, not currently making a legal claim.
Your target market would certainly associate the name with me and the site that I built, and I would prefer it if you were to make a clean break since I am not associated with the site.
Again, good luck!
