Are you in Texas? In Austin and Dallas we have formal training programs for both Doms and subs. It's a year-long program, roughly one Saturday a month with lots of homework, that runs Dec to Dec. It's super cheap, document fee and 8 hours of volunteer time. It is a lot of work. Class size is about 30 people. All the instructors/mentors are volunteers. None of us get paid.
I also run a for-pay academy for folks who can't afford to be recognized (politicians mostly) but it's not cheap.
I'm hoping this group can supplement or replace r/bdsmadvice for specific questions. What do you want advice on?
