User Group Promotions

I just set up my first user group promotions. Basically I set all users with the female gender to be added to a group that can see a hidden board that is just for girls. How long will it take to add existing female members to this user group? Will it make it their default user group? (I want it to be their default so the username color turns pink as I have it set to)
