Detentions:Feel free to give them! If the students don't want to go, fine, so be it, it doesn't really matter. But, if they do want to go through with detention, it'll just give them another room to meet other characters at, and a room full of trouble-making hooligans is sure to be interesting!
Here's the link to the detention room:

only from your class. They can still attend any other part of the school. Also, if you do decide to suspend a student from your class, it only affects that character, none of their others. Finally, suspensions will only last for a five days maximum.
Expulsion:No, you cannot expel students! If there is a serious issue, please message a staff member about it.
