Not sure what a domain name is?
It's a web address. Like www.GetMyFamilyName.com
With a domain name, you can have your own identity on the Internet, that is yours for as long as you own the domain name.
Domain Registrations are like registering your car. You have to renew every year (or register it for multiple years). Registering allows you to have a website with your own name, and most importantly, a PERMANENT email address for you and your family.
If you have YourName.com, you will be able to have email addresses like 'firstname @Yourname.com'
The names are going fast. Grab one now at www.7SagesDomains.com
