I would love to have a way to meet like minded people, and have some kind of official forum to chat in, swap ideas, hints, tricks, tips, or just brag. Some examples would be a Narrator's board, a D&D player's board, a board for each world, a board for world building, a board of art, a board for religious people of various belief systems (or for atheists), a board for feminists, a board for LGBTQ, (these last few could be really good, as they would allow players to find like minded players more easily).
