Snookr (dot) com your views/appraisals/development ideas/selling ideas would be highly appreciated =)
Well, the domain name itself is worth reg fee, IMO, because outside of the UK, and maybe some other parts of the world, snooker is not a known sport (like here in the USA). I would however think your domain would be more valuable if you developed it into either a games site or site with information on snooker!.
That name could possibly be branded out.... like - flickr.com ......It just depends .... Snook? Not so sure about that.
