I'm just posting this again because I've received half a dozen inquiries from new students asking why they can't see the school/common room/etc. In the sorting PM you received there should have been a link to the Hogwarts School FAQ that you should have read through and become familiar with. The answer to that question, along with some other very important information that you need to know. Just like with our site, we would like you to become familiar with our special rules and tips. Whenever you have a question, please check the FAQ (Frequently Asked Questions) before PMing a staff member. We can get a bit testy when you ask a Frequently Asked Question that has already been answered- it happens frequently (hence the name, Frequently Asked Question, and the FAQ that we took the time to write for you).
