I have just done my application last night. I did receive two emails, one a receipt of payment and another one exactly like Sara_and_lila confirming my application.
I got confused with the dates however. On the practical info bit it says first week is 1-6 July and when I applied it asked to choose between two weeks and the first one was 4-9 July so a Thursday to a Tuesday. Does anyone know what the actual dates are?
