Could you expand on this more? Like, do you get an error when you go in them, or are they not visible at all?
There should be 4 portals when you first spawn. 2 are in the cave, which is South Pole, and the other is Ficho Tunnel. That should be very close to the South Pole portal. Then there is another that's in the water when you exit the cave, and the final one is if you climb up the cave.
Hey, there's a guide here that will show you how to get to the other public maps, which you don't have to download ^.^ http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=24778.0 (http://www.feral-heart.com/index.php?option=com_jfusion&Itemid=2&jfile=index.php&topic=24778.0)
