I never got to play the game either. I am going nuts waiting for the game to work again!
I hope they don't let in people little by little. That would be unfair to people who don't have their own computer or just can't log in anytime so when they do get time to play FH, they might not even be allowed in! if that happened to me, whoever's in charge would certainly hear about it.
It might also prevent friends from playing online and doing activities in the game together.
They should just find a good server that will support all of the players, or develop a system with one server per group of players or world and each world or group can only hold so many members. That way if one server crashes, it's only one branch that's down, not the entire game.
It would be the longer solution, but the better one.
