Seeing how the stamp achievements category have been a bit neglected, I came up with a cool idea to help boost it. I reckon it would be a great idea to have a stamp that can only be achieved when you exchange a certain amount of letters with a pen pal. For this idea, I prepared a mock-up and as you can see, I named it "Slowsties" which originates from Besties* + Slowly = Slowsties. The stamp is to be unlocked after exchanging 50 letters. As I said, it can be changed to any amount the dev team see fit and "Slowsties" can be changed (although I think it's a brilliant name but I'm biased for sure). And of course the design could be improved, too. Thank you for reading. I hope you like my idea. *Besties = a person's best friend.
