Google plans to extend its private-labeled calendar, e-mail, and IM service to organizations without a registered domain name by helping them to register a domain name.
Google isn't actually becoming a domain registrar. Instead, it has partnered with GoDaddy and eNom, which will become the registrars of record. What Google is providing is an easy-to-use registration interface. The cost to register a domain through Google is $10 per year. Google Apps for Your Domain users have a choice of .com, .net, .org, .biz, and .info Top-Level Domains.
