The 4500 templates can be downloaded at templates.hdwebprovider.com. You must have experience using a HTML or Flash editor to customize the templates.
They are free to use for any site which is on a HDWEBPROVIDER™ server (even your clients).
These templates are not compatible with our site builders. Sitebuilder and SiteStudio have their own templates.
You are allowed 10 downloads during any 24 hour period.
Yes, you can remove the "Powered by HDWEBPROVIDER™" at the bottom of templates, and make any changes they want to the source code, but we cannot advise how to do that.
