Okay, so I go to my host, I register a domain name, I build a website...what if I want to sell that domain name? Can I? How would I go about transfering ownership? Just something I was curious about, was lookin for a little help if anyone could offer some.

Domain push - for the domain a lot of registrars allow free domain 'push' to other accounts. I register all my domains with either namecheap or godaddy and they both offer free domain push to other accounts, it is just a matter of whoever you are transferring it to going and setting up a free account. I'm pretty sure you can push the domain to another domain registration company but that usually costs money.

With another company it's a "pull" instead of a push; they initiate the transfer and it costs them money.
