, The way to tell IF they reset your 90 day reporting when you get an extension is this
IF they DID give you a NEW 90 day reporting receipt, they reset it and you follow the new receipt.
IF they DIDN'T give you a new 90 day reporting receipt, they didn't reset it and you follow the due date on your current one.
It's a simple way to know.. :P
