what is add enhanced plan
Originally x10hosting had a separate set of plans during signup, Advanced and Corporate, which required ads to be displayed, but they had more disk space and whatnot.
Due to a ton of users signing up for those then never displaying the ads, x10's changed how they handle ad-enhanced plans - you sign up for ad-free first. You can still get the ad-enhanced plan by logging into the account panel:
http://x10hosting.com/panel.php and getting the advertisement codes from there and placing them on your Web site.
Once you've got the ads displayed on all pages of your website, post in the Free Hosting section with a note that it needs to be escalated into a support ticket, and one of our users will get it escalated to staff so the plan can be upgraded to either Advanced or Corporate for you
