You may post information about a certain subject that isn't a class that is already taught, if it is something that is easy for us to pick up on in just one thread, go ahead and do it. If you are unsure of the matter, direct yourself to the discord server asking the headmistress (CrystalPink) about it. Other than that, if you are looking for more in depth information about a class that was taught in discord, feel free to lurk through here.
