B4U-ACT
B4U-ACT is a non-profit organization whose stated goal is "to make effective and compassionate mental health care available to individuals who self-identify as minor attracted people and who are seeking assistance in dealing with issues in their lives that are challenging to them." It was founded in 2003. The organization holds workshops to facilitate communication between mental health professionals and minor-attracted persons and to promote awareness and understanding of issues related to minor attraction.
B4U-Act was crucial in the popularization of "Minor Attracted Person" as a neologism - with Richard Kramer and the late Michael Melsheimer (who co-founded the organization with mental health professional, Russell Dick[1]) being possible conduits between the minor attracted community and the mental health professionals, academics and even journalists who went on to adopt and promote the term.
B4U-Act has authorized and promoted many studies for online MAP samples, and tends to hold a lot of sway over a study's deemed authenticity for a wider sample of MAPs.
