Probably I'm asking some kind of really stupid question, but how do I come back to town from the Wilderness? I can't find any commands and there didn't seem to be any portals around the spawn either...
You have to get back into a protected zone in the main spawn or one of the outposts(where you cant build and your health replenlishes) and there you can do /home.
Once you Enter the protected zone of the wild/nether you will be able to do /home to go home.This means that you don't need the use of portals, if you wanted to easily go to the nether/wild you would do: /wild or /nether.
