I have a .com domain that I purchased from another site...can I take advantage of the free hosting that x10 has to offer with 500mb of space with my domain? If so, do I need to pay a transfer fee?
Yes, set the nameservers of the domain to ns1.x10hosting.com and ns2.x10hosting.com if you can. If the company does not allow you to set nameservers or customize the specific settings, then... I don't know!
