They go by several names ... Domain Renewal Group, Domain Registry of America, Liberty Names of America and probably a few others that I'm not yet aware of. Regardless of the name, they operate in the same manner - by sending out what looks remarkably like a time-sensitive invoice for a domain renewal. But if you read the letter carefully, you will realize that they are using an approach called slamming (trying to trick you into switching your domains to another company). They highlight that your domain is due to expire shortly, and that you risk losing the domain name unless you renew the registration. Although the letter states that it is not a bill, it is purposely designed to look like an invoice. Paying that "invoice" actually begins a very overpriced domain transfer - and undoing that mistake will be a major hassle. Often the transfer fails, but the fine print says that the fee is non-refundable. If you receive an invoice from anyone other than your Web host or domain registrar, you'll save yourself a headache if you simply send it through the shredder. MOONDOG WEB HOSTING does NOT send renewal notices via postal mail.
