Dear Nuuni,
I came out to about two hundred people, some by letter. I found it most effective to show my emotions, tell the choice that I felt I had in life. (being socially acceptable and miserable or taking a giant risk to be myself) People responded to hearing that choice and the pain I faced. The problem is that if you do this, you are being pretty vulnerable and at risk of someone hurting you with that info. You need to measure the risk reward. I would think it smarter to limit specifics. Many don't want all the details and it lessens your risk.
