I've received a request to renewal my domain at 'Domain Registry of America' - should I do so?

In nearly all circumstances the answer is no:

If you have purchased your domain directly  from Supanames, then as a SupaNames customer, please only renew your Domain and hosting through us using our renewal link as sent in your renewal reminder e-mail.

If you have your domain held elsewhere, and are pointing your domain to your SupaNames Hosting by way of a Nameserver change, then please only renew your domain with your domain registrar, and your hosting with SupaNames using our renewal link as sent in your renewal reminder e-mail.

Unless , in the unlikely event you have purchased your domain originally from the Domain Registry of America, and are pointing it to your SupaNames hosting, then no payment should be ever be made to them.
