For most people, this is their most important function. IFGE maintains lists of groups all over the country. It is a good idea to call the group and ask what types of activities they have, what their requirements are, dues, and where they meet. All support groups realize that a member's identity is a personal matter and must be kept secure to protect their family and job. In general, their membership lists are not made public to anyone.
Different groups adopt different policies for the security of members.
Usually you will be made aware of their security practices when you call. This is a common concern with all support groups, so don't hesitate to ask. Won't it just go away. Many people deny the desire to crossdress for years. Denial is a safety mechanism which works, but not in the long term.
