So did I when I first joined it, we never made it about sex though, There was one sex scene between our character but now its been open to jump in ever since.
And it wasn't dragged for pages like some people do. So anyone could have joined in at any point, especially since no one is playing a teacher, ghosts, the paintings, then of course other teachers.
We are both out of idears trying to keep it open for others to jump in when ever they want to join in.
Will add a message to it that way it might attract others.
If you mean charater wise there is loads.
Students
Staff (but if you are that please add the subject so i can put it's taken)
Ghosts (Again if your a house one add that please).
