Do I need to renew my domain to keep my e-mail address?

A number of these renewal "scams" have been going on for years. I did a WHOIS on your domain name (yates1.com) and it showed an expiration date of 4-6-2008, so you are not even close to your expiration date. At the appropriate time you should get an e-mail or letter from yahoo telling you your domain is about to expire and how to renew. It costs at the most ~$40/year to renew a domain name and less for multiple years. Ignore the e-mail from domain listing center.
