Hudson’s FTM Resource Guide: Very informative, specifically for ftms. A great starting point for aspects of the transition you don’t know much about.
Transgender Legal Defense & Education Fund: organization “committed to ending discrimination based on gender identity and expression and to achieving equality for transgender people.”
FTMTransition: Great blog by a trans guy. I, personally, found it very comforting when I first began to look into trans issues.
T-Central: “Just a mondo but not complete listing of Trans-Related Bloggers and News Sites.”
Transwhat?: “A guide towards allyship.”
