Renewing every 14 months after getting a reminding e-mail isn't too bad, IMO. Compared to many other registrations they only ask for a valid e-mail address to send the code to, name (any name will do;) ), country (for statistics, I suppose) and an agreement tab that you aren't using it for business purposes. Highly recommended! Modificable, multilanguage, lightweight and -best of all - free.
Besides, absolutely no security program is 100% reliable.
