We have a new guest spawn house now behind the portal house. When guests spawn, they will see a sign that asks them if they want to see the best builds or find a lot. They choose two other signs accordingly, one will tell them about the /warp command and the other will tell them how to warp to the portal house.
So we got rid of the issue that people cannot find a portal house and a generally better guidance for new users. If you see that new users have issues with that, please report it so we can make improvements.
