Since, you only recently registered the domain, ask Encirca to cancel the registration and refund the fee. As I understand the terms of the "Pro Forwarding" Agreement, Encirca, as the registrant of record, is under no obligation to defend any given trademark action. Nor, is there any reason to believe that they would defend this particular registration. Further, as I believe was alluded to in an earlier post, the registration does not make for good publicity. Do yourself a favor and secure your refund today...
