They claim to have 5,400 memebers, but none are obligated to move at this point. The Exodus is supposed to begin when the numbers hit 20,000. None the less some have begun. The vote was held to pick a state last fall, when they hit 5,000 members. Things seem to have slowed down since then, and also many of the 5,000 had "opted out" meaning they said they would not move if a certain state was chosen. Thus the actual number of committed memebers is probably much lower now.
