My idea is a shop sign with two people on it. The end. But seriously, my idea would allow two people to be part of a shop, so profit is split equally. Essentially, only the original shop creator cold set it up, but you would put the player you want to share profit with into the top line instead of leaving it blank. If the player exists, then they will show up and won't if they don't. It has almost no possibility to be abused, because if you want to share a shop sign that buys items the business partner must give consent to give half the rupees to buy the items via either a /promo like toggle, or mail. There could also be a player setting to require consent for shops that sell if you are worried about people abusing your username. Either way, you would get a book with the names of the people that shared a shop with you for the past day and how many. Since you would only get the book once a day, you will not be able to spam anyone with mail.I will clean up the block of text later.Post any improvements to this idea!
