Right after the registration, a directory for your site is created on the server. This directory contains a temporary index page that is accessible from the internet and allows you to:
administer your user account. Enter your control panel login and password into "Login to your Control Panel". This login and password are e-mailed to you at the address you specified at signup. Use the Control Panel to view your bills, change your contact/billing information, change passwords, get more disk space, report problems to the technical support staff and much, much more.
create a web site in a matter of minutes right from your browser. Use the option "Launch Site Builder". Initially, the password to log into the site builder is the same as that for the control panel.

Whenever possible, upload your site using the utilities that come with your web-site development software. For instance, if you made your site with SiteStudio, FrontPage or Dreamweaver, use their integrated web publishing tools. If you made your site with simple text editors, or if your site-building software does not have a publishing utility, use freestanding FTP clients, such as CuteFTP, SmartFTP, or the built-in web-based FTP agent.
Please note that site publishing tools don't remove your old web content from the server. For instance, if you used SiteStudio to upload a site with 15 pages and later you published an updated 7 page version of this site, your directory on the server will have all the new pages and the old pages that haven't been overwritten. If you publish many versions of the website, the site may become cluttered with old files. Warning: If you have a complete website, be careful not to overwrite it with a publish command.
Don't upload your site to the root of your user directory! Instead, put it to the specific directory.
