Re: COMMUNICATIONS
Tonks couldn't really think of any spells at the moment that could that: since it's based on self-identification, the magic would need to be able to identify a part of the individual's identity. She's not so worried about encoding the "dissuasion" part, but she does wish they could include some more specific details on how Muggleborns can gain access to aid, for their eyes only. She wondered, though, if it might be similar to warding--can you ward just Muggleborns? OR the Marauder's Map uses a password. If they had a password-protected message, could they get it out securely?
