Antijen is run by Aunty - who hosts many lists relating to transitioning for both families and the person in transition. It's a great resource with very nice, understanding people behind it.
It is a place where the transgendered can come and get love and support from their peers, and hopefully soon their friends. A HUGE resource with FAQs, experiences, news and resources.
As well as transmale and transfemale lists, there is also a Significant Other and a Family list.
