Every web site you create in your account comes with a temporary URL that you may use to view and troubleshoot your site before your domain has had time to be pointed to our servers and propagated.  The temporary URL for your initial web site (the one you signed up with) can be found in your welcome email.

To determine the temporary URL for any other site that is set up in your account, pull up the 'Web Options' screen for that domain from the control panel, scroll to the very bottom, and look for the 'Instant Access Domain Alias'.  Click the magnifying glass icon next to this address to launch a new web browser pointed to the temporary URL.

You can then bookmark the page from your web browser.
