Yes I'm still accepting. :) Please post a character idea up in here for review, or PM it to me.
MedicalMiracle: Well, the game is set in the town of Maneflow, which has it's own post office with a spacy deliveryman. But he's only one pegasus, and an NPC at that. I see no reason why you couldn't have make someone like Derpy Hooves if you wanted, and make him or her a postal worker. After all, there's more than one mailperson in any city in real life. :)
