Once you have signed up and an account has been setup, you can access you cPanel by pointing your browser to:
http://www.yourwebsitename.com/cpanel/
If you have recently changed your domain name Nameserver settings to point to ANC and they have not yet propagated then you may access your cPanel through:
http://www.anetcompany.net/cpanel/ and use your login username and password to log into your cpanel.
NOTE: Namserver settings may take up to 72 hours (3 days) to become affective.
