The number of websites depends on the type of license you get. By default, we have three options: single site license, license for five websites, and the license under ONE Membership. With the first option, you can use the template with one domain name but with unlimited subdomains. So you can install the skin that you like and use others on subdomains for the test or other purposes. The second one, also called “Developer’s License,” lets you use the theme on fice different domain names. With these two types, you still receive lifetime updates and support.  When it comes to Membership, the situation is a bit different. You can use the template with unlimited domains number, as there are no limits on it in ONE. But you get updates as long as your membership is active and free support for one year.
