There are several ways to access the control panel:
https://www.yourdomain.com:2222 You can access the control panel through any domain or subdomain by putting :2222 after the address.
https://192.168.0.1:2222 You can access the control panel through any IP address allocated to the server. This is useful when your domain transfer has not yet propagated.
A window (similar to the one pictured above) will appear. Enter your username and password. Once signed into the control panel you should do two things.
First, click on the ESSAGE link at the top-right of the page. Important messages about your account may come through the message system, so we recommend that you enter your e-mail address. Scroll at the bottom of the screen and click OPTIONS. Now find "Email a copy of all messages to" and confirm that e-mail address in the box is accurate. If you do this, the control panel will e-mail you when a message comes in.
Second, return to the main menu and click on the "View More" button in "Your Account" section. From there you will see "EDIT ACCOUNT INFORATION" button. Confirm that the e-mail address in the box is accurate. If not, change it and click on the "Save" button. It is important to have a valid e-mail address in this box because the control panel will e-mail you whenever your account is close to going over its bandwidth limit.
