We don't discuss other sub's at this site. But to add a new portal simply go to the inner portal by pushing setup on the remote. Then there is an option for portals.
Thanks wickedjoker, let us say one portal for NPFS and one for Rocket, I know it doesn't make sense, but for an education purposes, so, I added 2 portals, now how to tell MAG which one to start with every time I turn it on?
