Developing this as a new business idea can do wonders... As earlier said, this can be some game site or Raffles site , plan your work and work your plan
Depending upon how well its developed it can we worth upto high $xxx
Personally I believe this to be an outstanding opportunity if infact all the legalities are explored and a well thought approach established. This is a very tough domain name to appraise given the fact that the real pull to the site will actually come from the domain names someone might win and their quality....does this make any sense? I have noticed alot of auctions these days are somewhat stale and this fresh new approach my be a perfect money making solution. I personally would pay $1 or $2 dollars for a chance to get a premium domain say like earth.com? Advertisement would play a key factor....maybe a commercial or two? Oh well this is just a humble take on this so thanks for your time, Doug
