In my experience, no one actually reads what you write in the OP. If it's not in the title, just assume no one saw it. ÂŻ \ _ (ă) _ / ÂŻ
That's actually different, since ATM is not pronounced as its own word; people just say the letters. Like I used to say "G-I-F" when I was younger until I realized no one else did that. ^^;
A better example would be something like NASA, where the first A is for Aeronautics, so if pronunciation accuracy is so important, people should be saying "naysa" and not "nassa".
