I think this thread is worth sticking.
Lets suggest ideas for boards we would like it to exist but we don't have the knowledge/time to create it and be moderators, but sure would be constant users and maybe lesser moderators.
Support posts you find interesting in some way so that possible board creators can have an idea of what boards would be more demanded.
I think a board for discussing relationships would be interesting, a place to get tips, ask for help, etc. I thought on this as a board for marriage/relationship situations, but I think it would be ok to let any kind of close/personal relationship to be discussed (family, co-workers, friends, etc). It would also be better as a SFW board.
