You also must be a Pureblood to join the D.E.A.!
The School Has Not Started Yet, so please don't send any forms quite yet. Sorry.
Once I have emailed you back, you can start doing you homework! There will be 2 homework assignments a month. If you don't complete your assignments you will be held back a year. And you must include your house password, or your email will be rejected!
Your best regards,
Headmaster Marvolo
