When will the queue start?

When will the queue start? Lets say a server has a queue, when will it start?

A: When you try to open the game and get into the character screen
B: When you select a character and get into the world?

If its A, its going to be a pain to create all your ALTs from the start

The route is this:

start game->select server screen->char creation

queue likely at select server screen
