There is no such thing.
When you are a member you can download the templates, demo pack or extensions that are included in your membership and use them on as many domains as your membership level is covering.
For platinum members, 5 domains but for developer members unlimited + you can remove the YJ copyright from the websites you develope as a developer member.
After your membership has expired (after a year as platinum or dev) you can still use the YJ templates and extensions on your websites but only on the domains you assigned them to as a member.
(The YJ contact Us form is not included but you can get discount on it as a member and it is inbuilt into one of the demos)
Hopefully this explains well enough.
