CSGT,
For those who have the appropriate position on C1 "Positions and Appointments" they have access to the "Mail Distribution System". To my knowledge, these appointments include: ADMINO, CO, XO & SQNWOFF. It has been limited to those positions as they are they points of contact you need to speak to prior to sending a squadron wide email, as they will (generally) be the ones to have the 'yes' or 'no' say so before it's distributed. (And also because you, even though an CSNCO, are still a cadet member - not staff). Which ultimately bubbles down to the Chain of Command factors.
I could be wrong, however I'm under the impression that that's the proper protocol.
But from one who holds two appointments and does not have access to this when I need it, I second your idea!
Cheers
