No one I know has received an attatchment email. Nor I. I received an email today with a confirmation of tomorrow, but nothing attatched. I would not worry about it. If they wanted people to have it and have things printed, they would have sent it by now, as it seems no one has it.
They will have everything organised tomorrow.
Im not going to worry and stress about it. I have all documentation anyway ready to take.
Good luck all.
