The posers feature temporarily protects unregistered players.
Once you start a game, even if your player name is not registered,
no one else can log into this site,
set their name to yours, enter the game, and take your turns.
However if your connection drops, you can reload
this url and reset your name, reenter, and begin taking turns.
This works because this site recognizes you.
Occasionally, if you're playing with an unregistered name, you may want
someone else to be able to log in, set their name to yours, and take over
your position in the game. To allow this, someone already in the game
could click [Allow Posers].
