The email arrives a day after the letter.
It’s a simple welcome, followed by a link. The email is from someone calling themselves “MBR”, but there is no other hint as to who sent it or how they know who to contact.
If you are a Muggle who follows that link, you’ll get a 504 error message. This is a precaution, instituted early in the website’s genesis after an email was forwarded accidentally to a non-magical friend. The creator would prefer to minimize the number of Memory Modifying Charms they have to perform.
If you are the proper recipient, you’ll arrive at website and feel a frisson of energy. It’s nothing that can be explained by logic or reason, it’s simply there. Push a little with that deep wellspring of magic inside you, and the website unfurls.
It’s a message board, simple and straightforward. There are topic threads on where to get used books, what the Houses are really like, advice on classes to take after third year, career options for after Hogwarts. There’s tips on how to jailbreak your iPhone to make it play music within the castle, candy reviews from Honeydukes and comparisons of the offerings from Zonko’s and Weasley’s Wizarding Wheezes.
All of those who receive the link to the website are Muggle-born. They are children raised on the web, who think to go to Google before the library, who write with a word processor rather than a quill. They are entering a world that is, in many ways, decades behind the one they were born into. The message board was designed to ease that transition.
Whoever MBR is, there are hundreds of students who would like to thank them.
