If you are interested to test the Networker, you can use it on a test server.
An online tutorial is available at https://doc-r.infoloom.com that will guide you into some of the functionalities and explore different scenarios of use.
The same functionalities are shown as videos on the Demo page.
You will be able to access all functions for a limited time, for the purpose of evaluating whether it fits your needs.
Please note that the data you create on the test server will not be preserved.
