Hello,
Do you want to:
a) Use your .com domain on your site (so going to gr2london.com visits your website instead of the exofire.net)? If so, see our instructions on
using your own domain, or
b) Actually transfer the domain from where you bought it to x10hosting, thus making x10hosting the domain registrar (this is NOT necessary to use the domain on your account). To do this, visit
here and choose the "I wish to transfer" option. I believe the cost to transfer a .com is $9.95 and it will renew the domain so that it expires one year after the transfer date.
