This plugin loads a (remote) page in the dashboard of the user. The main purpose is to be able to show all your clients the same dashboard welcome, while you\’re still able to update the content of the page on a central location. 
While it works without it, it is designed to work in conjunction with the module RBS Remote Dashboard Welcome Control (https://roadbearstudios.com/plugins/rbs-remote-dashboard-welcome-control).

RBS Remote Dashboard Welcome

Load a Remote Dashboard Welcome page from a central server to show to your users on their own website.
