Simpler solution: No salutations. I called a friend "Ms ..." once - she was quite offended, though she chided me in a humourous way. She is quite proud of being "Mrs ...". So if you eliminate Ms, you eliminate her from your user base. And it is NOT your job to drag people kicking and screaming to your view of The Right. I happen to prefer using Ms, for the very reasons you state. But it would be patronizing in the extreme for me to use Ms instead of Mrs when Ms offends. Or instead of Miss. If you are not going to have a comprehensive list of all possible salutations (including Rev, Father, Your Holiness, Minister, Prime Minister, Honourable, Right Honourable, etc., as suggested by another comment, then have none). I find it creepy when machines address me by name anyway. I shudder every time my ATM displays "Thanks, Peter". I would much prefer "TD thanks you for your custom" - or something less archaically phrased.... :->
