Students can form groups when they please (we can’t stop you!). However, if you wish to create one to be associated with Mischief Managed, it must have at least one Admin in its membership. If it does not have an Admin’s approval and membership, it cannot be associated in any way with our sim. Any group that will affect a majority of students, has a large impact on a sim-wide event or to participate in a current plot line are required to possess Admin approval. If your group is found to be non-canon, dangerous and/or unlikely to happen within Hogwarts then it will be denied. Contact an Admin for more information!
