Great question... posed by a good friend of ours (you know who you are LOL). Sovereign House is not an organization like TES or Black Rose or The Boy Scouts or Young Republicans etc etc... There is nothing to join... no dues to be paid.
To explain Sovereign House is a bit complicated as we are still very young and deciding what exactly we are as we go along.
What we do know is the original 6 founders felt a special kinship with each other that went far beyond usual friendships. This is mostly due to the fact that we are all already related as either husband/wife, boyfriend/girlfriend, Master/slave, long time friend or yes, believe it or not... sister/brother. Hence we were already a "family" in spirit and we felt we should become one in name to help us serve the BDSM community and each other.
Once we started the family, one of our first problems was... "How do we/do we add new members"? We decided that we would never find or even want to find others with the same sense of commitment that the founders have for one another, but we WOULD want to add people to the family that we felt were like-minded souls that would still be part of our lives 10 or 20 years down the road!
So we have decided that we will take our time and be very careful about adding new people into the family. Each new member will be someone that at least one or more of our members feel "Married" to in one sense of the word or another. Just like a real family!
This all said we also want to find a way to honor our close friends as well as the people we admire and respect in the scene. We are working on a "Friends of the Family" idea that we hope will help us do this... we just don't want it to come across wrong and sound pompous so we are discussing it currently.
So, to answer your question... if for some reason you feel you want to associate yourself with a bunch as insane as ourselves I strongly recommend that you check yourself into the first quality mental institution you come across! But if I can't talk you out of it and/or you feel strongly about being part of or even deciding if you want to be part of Sovereign House, then know that Sovereign House is about friendship, loyalty & BDSM and the way into our family is to follow this website, communicate with us, hang out with us, be part of our lives and become our close friends.
