RPL User Management system builds an additional level of control on top of the Joomla User Management System in relation to RPL functionalities. This means that all RPL users are Joomla users, but the RPL user needs to be activated in RPL to be able to interact with RPL functionalities.
There is an Automatic Activation plugin. When it is activated, it will automatically activate the new Joomla registered users in the default group of RPL. This plugin will be installed automatically at the time of installing the RPL core component.
