Excellent question!
The world is ready so far. Spawn is set and a decent amount of world is ready to be explored.
There is just some arguing going on in the admin forum about how the "Spawn-City" should be managed, if there should be lots people can use, if yes do they have a inactivity limit, how wide the streets should be and stuff like that.
So.. yeah.. no idea if I can let people in yet or if the other admins want to have the Spawn-City stuff written in stone first. I'll have to get back to you on that.
