Master Template
The Master Template is the official reusable source. It has its own identity, version, language, and public presentation.
Your list
When you use the Master, Send Listy creates a new list identity for your working copy. Your list can be edited, saved, synchronized, and shared through the normal Send Listy list system.
Independence
Your copy keeps a reference to the source Template and its version, but it is not the Master itself. A duplicate user list also receives a new list identity and a new sharing identity rather than reusing the source list’s public link.
