Installation and Configuration
What that location is is the location to GET your license for JR5 and JR6.
When you put that info into the MARKETPLACE module in your Jamroom 6 site, it will be able to connect to the jamroom marketplace here on jamroom.net to install new modules.
When a site makes that connection to request the installation of modules it will be added to that section. So in order to add a site there, all you have to do is setup the site and add your marketplace key to that site.
ACP -> CORE -> MARKETPLACE -> TOOLS -> MARKETPLACE SYSTEM -> enter your details
JR4 doesn't have this system. JR4 will only work on a server running PHP
below 5.3, so will be hard to locate a server company that meets those needs. You will probably need to run your own server (not a shared server).
