>No, I saw it written. I'm almost positive that we're speaking about female, but in any case, I forgot where exactly I saw that position. I need to search for it again. I guess if I find it I would write Dear Ms. ... with 2% probability of a mistake.


Look. Write to Ms XXX. Serves him right if you're wrong, for not making it clear he's a Mr. If I were a Hillary, Evelyn, etc, one of those ambiguous names normally attributed to a female then I'd make it clear that I was a man.
