2) Portals
Open the map in mapmaker and open the third tab. There is an option called 'add new portal'. Before you click that button, enter the destination map and destination coordinates into the boxes.
When typing the map name, make sure it's not the display name and it's completely right including upper/lower case.
To get the coordinates, open the map you want to link to and place the cursor where you want to arrive. The coordiantes appear in the small brown box at the bottom right.
