Title: Anonymous Messaging Option in Secret Societies
Summary: Just as there is a way in normal messaging to pay for your letters to not include who it was all sent to, I think that while in a secret society it should be possible for messages sent in a secret society to be "anonymous" as it is in the underground. Either via a small payment to make it such, or simply an option to select.
Details: It could be that these messages are only anonymous to those who are on the same level or lower than you in the secret society hierarchy. Or that all messages are anonymous except the elders will always know who sends what.
Benefits: This would allow secret societies to function a lot better with actually maintaining the anonymity of members in the society instead of ruining the knowledge of who is in the society as soon as you use it to send a message.
Possible Exploits: None.
