I agree. The mail system shouldnt be linked to the defective chat system in the game. It should be its own system, with paper, and or envelops that can hold paper or coin for sales/goods that can be exchanged between players that dont play on the same time schedule.
-Envelops, act as a chest of sorts. Can open to reveal a paper and/or coin/products
-Paper, for letters…
Books would be great too. Although I don’t think adding images would work. It would require storing those images on a server. And those take up a lot of space. Then there’s issues with copyright and such. It be harder to police.
Maybe they can support more ascii characters. And people can make ascii art.
