Can anyone tell me what is the case if entries are extended and during that extended time you win out of the class you have entered for the forthcoming show?
Is it the original closing date that counts or is it the exteneded date?

As far as I am aware, the scheldule will state the qualifying date and this stands,its isn't affected by a change of entry closing dates as the period of time between the qualifying date and show date hasn't changed.

The qualifying date is a week before POSTAL entries close.
