It is set in the ministry of magic and allows people to rp adult witches/wizards (as a disclaimer, I don't actually rp there myself, so can't give more detail than that).
oh, i think a lot of the real life face claim harry potter sites focus on adult life actually, there are so many of them and i can give some advice too. but they probably meant it to be animanga fcs since animanga puts more weight in action side of things and less on the stuff like applications. they can correct me if not though!
that said, i also support adult wizarding world still.
