I saw a player with a yellow username. What does the color mean?
This player is a game administrator. Only administrators can get yellow names.
How do I change my username?
Please contact an administrator. If you were taken here from the username bug, please take in mind that setting a new name will create a new object and your account data might be lost. Contact us to allow you to safely change your name.
How do I get more worlds?
You have 26 worlds, 4 of each type, which is more than enough. We may only give extra worlds (which won't appear in your world list) on special circumstances.
