Hi,
Easy Profile extends Joomla User Profile, so registration and edit profile pages (frontend and backend) are the same of Joomla.
It is basically a profiler component, so you can manage your custom field. To do this you can access on backend to Components->Easy Profile (as all Joomla components)
You can get an overview of the features going on Components->Easy Profile->Options (as all Joomla components)
To set lists/search users page you can create a menu item of type "Users List" or "User Table". (all Joomla components manage view by menu items)
Its interface is the same as that of the management of Joomla articles (creation, modification, sorting).
for example: EA users are on different tables from Joomla and need a sync ?
this is not something that is written in a standard documentation, anyway, you don't need to sync users. All custom field data are stored in #__jsn_users table, this table extends Joomla default user table.
For specific question feel free to contact us in this forum.
