Retirementcommunity.com is valued by Estibot at 170,000 USD. My domain is the short version of the two. If the Gtld market continues to rise, then the next owner will be happy with the results.
Even you don't know what domain you're selling....Community or .Communities.... and also per forum rules you're suppose to have the domain you are selling in the title and not a name you do not own.
