I agree with glorifierx. 3 letter .com domains are rich in value. list the domains for sale.Hope it get some decent price
Having a three letter .com domain is a great advantage. There are few, if any, common letters and few letters .com domains available. You have the advantage of having two such domains. With imagination you can market anything with those domains. For example: LNL.com could be London NeuroLingual site. COU.com could be Canada-Ottawa University site. Look to see if there is any company or corporation that could profitably use those domains and make them an offer. Just my opinion... Sincerely, Antonios
