i'm trying to do this now, I'm slowly getting rid of people I don't talk to and have to delete and hide all old pics of me when I was in "fake girl mode"...not as easy as you would think, so many pics, I did change my profile pic to the one i'm using here and no one said anything negative, got a few likes, i changed the gender thing to hidden and made it gender neutral for now, so facebook will be like its their birthday today, instead of he or she, I also turned my facebook name to my nickname people usually call me, so I didn't have to keep seeing my obvious female legal name, its a slow process right now, I figured once I been on T for a couple months and can pass more, I'll end up changing the name and gender to male on facebook
