I am new to Susan's, however not new to transition. I would have never considered to look at or contribute to the FtM board. It wasn't my interest since I am a MtF. It didn't even occur to me that I might have something I could have added there considering I spent 30+ years pretending to be a male.
If I had the time, I don't think I would be bothered by reading/contributing to that board. I hated my male body/gender, but I still acknowledge that I had it, lived the first 30+ years of my life in it, and now I'm just moving toward the life that is congruent with the person I always knew I was. Since I totally support helping people in anyway that I can, I would contribute if I thought I had something semi-useful to add.
