I can almost hear it now, the utter confusion of "why so many sticky threads in the main forum!?". Trust me, it takes a little bit of getting used to, but it does make so much sense over the long run when there will be more and more users posting at the same time.
To put it simply, the threads are spread out to cover all areas of the Campus. In the main forum are the different Halls, so users can post as students in those respective areas. When students move from one area to another, they post in that section. When you are in the same area as another user, please remember to quote them to have a reply in a timely fashion. If you move across to the dorm room that your character owns, please post in the Dormitory Section. The Dormitory Section is also where users can post as students in the Student Lounge, Shower Hall, or Laundry Services in the Dormitory Buildings.
Students must also be enrolled in a weekend class, an Extra-Curricular Activity, of which they can choose from. There are several "main" activities that are popular amongst students, as well as options for recommendations. Students must remain with an extra-curricular activity for the term, but may switch once the new term resumes.
If you have any further questions, please let me know!
