Hello,
I want to create few slave sites, whose users will be synchronized with Joomla and Easy Social users on master site.
I have difficulty creating a template.
Maybe I did not understand something.
If you can help me?

The concept of JMS is based on the sharing and NOT on the duplication of content that require synchronization.
JMS does NOT contain anything to synchronize.

When JMS share the content of an extension, it creates a kind of link between a MySQL table from a site to another one.
This is managed by MySQL and decided when the slave site is created.

See the tutorial video 16 that show how to create a slave site that share the users.
www.jms2win.com/en/tutorial#jms12x-16

When the slave site is create with a sharing, you can see the link via the JMS Tool menu.
Click on the slave site and you should see the hierarchy and dependencies and also the links between the MySQL tables
