Hi Socialflyer THAT SOUNDS GREAT!!!
I don't know much, if anything about how Eastern recruit... I think SydGirl works for them actually.
I must say by them saying that if you get the big envelope its good, if it's small.... it makes them sound relaxed, funny.... hmmm I don't want to get your hopes up more.....but hey it really sounds like they liked you and to joke about the envelope!
Oh fingers and toes crossed for you.
