Starting now, if you would like to maintain your free Dyn account, you must log into your account once a month. Failure to do so will result in expiration and loss of your hostname. This activity helps us eliminate hostnames that are no longer needed and/or dormant. Note that using an update client will no longer suffice for this monthly login.
I received an email from dyn.com (aka dyndns.org et al); apparently they're going to free require users to manually login every month or they will expire accounts. (emphasis mine) Barry
