When setting up a host as a partner the host is automatically set as a partner free test host until release. All our partners have the access to set up development hosts for free until release. The host can be transferred to your client when your new project is ready for the public.
Setting up a host is easily done by going to hosts in the menu and clicking on the add new host tab. Fill inn the information and you are good to go.
