I dont get it! Whenever I make a game it says please enter the game world you want to be in but it doesn't have a list or something i can type in! What do I do?

Ah shoot, okay! I think what's happening is the gateway isn't up. There is an autodetection routine that is supposed to be able to alert me if something goes wrong with the gameserver, but I think it's down.

Quick answer #1:

Right now you can install world packs manually and install them using the setup tool! Just click "View Worlds" on the website, then download the .gz and install using the setup tool (from the Windows Start menu)

Quick answer #2:

I am really really sorry! I feel incredibly bad, I've been a little too "lax" with making sure things are running well on the server side. I will get everything up and running today with online play.
