2021 Founding Sponsors

MTTA is an all-volunteer, non-profit 501(c)(3) educational organization dedicated to consensual Master/slave relationships. Founded by Master Taíno in 2004, MTTA is governed by a Board of Directors comprised of leaders in our Master/slave community. MTTA is dedicated to providing educational, training, social and networking opportunities for adults interested in alternative relationships. It’s programs include the Master/slave Conference, MTTA Academy, M/s Legacy Project, and Master/slave History Program.

∞♥∞ The Poly Exchange is dedicated to education and support for those interested in the intersection of Polyamory and Authority Based Relationships. Our mission is to provide an interactive forum for those with this shared interest to explore, learn, share, and discuss this particular juncture of relationship dynamics. The Poly Exchange celebrates and passionately advocates for diversity. We are committed to fostering an inclusive safe space for all orientations and identifications to engage in meaningful discourse where these consensual relationship dynamics can be talked about openly and authentically.

Far too many in our chosen families have already been lost to us with precious little of their wisdom preserved. Our Leather Legacy is dedicated to collecting the teachings, lived experience, and perspectives of important voices in the Leather and M/s community so that more of their insight and understanding can be made accessible to future generations.
