First, check to make sure that in your cPanel File Manager's public_html folder, there is a file named "index.html" (or "index.htm", or "index.xml", or "index.php", ...) depending on the markup/web language that you're using for your webpage. These are the valid names for your first page (NOTE: file names are case-sensitive, so "Index.html") will NOT work,
To view your webpage, simply type "yoursite.x10.mx" in your web browser's address bar (where "yoursite" is your user name, and "x10.mx" is any one of the following free X10 subdomains "x10.mx", "x10.bz", "pcriot.com", or "elementfx.com" that you've chosen for your site when you first registered, and that's there is ALL to it.
If you have put a "index.FILE-EXTENTION" (e.g "index.html") in your "public_html" folder, when you login to your account at www.x10hosting.com and click "hosting" in the top bar, your website link will be in a link next to "main domain:". Just click it!
