Domains are not provided on free hosting, and its unlimited because the more bandwidth you use, the more money we make from ads. On paid hosting, there are no ads so you pay yourself for the bandwidth you use. Most of the features of paid hosting won't work without a domain (email, fantastico, etc..) so you are required to purchase one. Paid hosting offers cpanel, so you need to sign up for a new account (we can't move over a non-cpanel account to cpanel).
