The ability to create letters and write them as well as send them threw the mail
After listening to the last Alta cast, and hearing how they used rope instead of scrolling… it got me thinking: why not add a new device such as a type writer that we could use to turn papyrus into messages? Even if there’s a character limit. A type writer fits the ascetic of township rather well and it could make mail more meaningful. Such as giving a reason why your sending Bob the black smith 15 iron and a handle.
-each letter should always add the signature of its writer for moderation purposes on the bottom right corner.
Personal twist (optional)
Other than sending it in the mail… why not stuff your message in a empty bottle? This could be a fun interactive thing to have fur treasure hunts or even just find them when digging into the earth with a shovel.
