you have over a month to select your world
I can not find anywhere that ppl can select their world now already, what I read is that ppl have to be online during those 9 days or else will just being randomly distributed across the worlds.

What bothers me with this is that ppl are getting forced, SE shows us that migration is possible, why set a time limit? If a server is full fine, but give ppl the (paid) option to server transfer at a later time.
