such a cool addon, the items are well made too

I love that you made a mail system, I was wondering if you could possibly make a fantasy version of the mail box, like a raven rookery (example when you send the mail the raven makes a high-pitched squeaking sound when leaving and once arrived it will make a squeaking noise to nearby players to be notified that mail has arrived.)

I would love if you could make this in some way I host a fantasy RPG/RP world, and I like the system you made, but I would love if you could make a fantasy type mailbox for the people who make fantasy type worlds?

I currently have a few other projects in the works, but I definitely think that would be a fun addon to make
