Under the calendar menu you can find the off-sim calendar request form to have any off-sim events added to the Mischief Managed calendar

Whilst we have previously not sanctioned off-sim events as MM canon we’ve changed that to continue to expand our community by linking events to Mischief Managed. Only Expecto, Patronum, and MMIII are official Mischief Managed sims, on the occasion that a fourth sim is used for official Mischief Managed events they will be announced by admins.

By holding any event off sim that is linked to Mischief Managed you agree to abide by our sim rules and any roleplay that does not fit into HP or MM canon, or if there are concerns with happenings off sim, may be voided.
Points for roleplay cannot be requested if the RP is not on an official Mischief Managed sim
