Question

Question:Can I create a classroom? and like be the teacher and teach?

If you mean in the Great Hall section like others have, then yeah. But if you mean in general, then I dont think so.

Like violet said.

If you are talking about the RPG section in the Great Hall then you can.

Though the Official Classes in Hogwarts Experience where points are given then no. From times to times a professor steps down and that class goes up for application, only the person who gets the place is allowed to then post classes.

You can participate in classes though as a student any professor will happy to have one more student doing their classes.

As Violet said, the great hall is our RPG section and you may create any posts there you wish to benifit RPG stories. Take a look in the relevant subforum in the great hall to see how others have done it.

If you are meaning actual classes on the site, then no. Classes often have vacancies if a professor steps down from that class, which you may apply when you are 2nd year and over. Any new vacancies will be posted in the ministry of magic subforum in the notice board forum

Quite often we bring new classes to The Hogwarts Experience, and all ideas for new ones are welcome in the heads of house office
