That's pretty weird. I want to regsiter a free domain with the package "Crazy Insane". When signing up, I type the domain "example.com" and it says it's not available. After, I check under the "Domain Registration" section and I type "example.com" and it says it available! I also checked on GoDaddy website, and it's available.
What's wrong? Why a domain is available and not available on the same hosting website?
