The problem with this domain is that the World sees it as bronzeaccount = 3rd place or 3rd level account. It's almost impossible to escape the 'Sporting Synergies' Purely because 'Bronze' as a word mostly has its associations with bronze artifacts or sporting achievements. Now if Bronze were a precious metal valued by investors you'd have a worthwhile domain. Personally I wouldn't have registered it in the first place and I don't see you even getting your registration fee back.
Platinum, Gold, Even Silver account. is as far as it goes for domain names
