I've got a game where players can create trade offers. Other players can view all of the available trade offers in the game and accept the ones that they want.
I'm just wondering how this could be done using the Trading system. Currently I'm thinking of having players create an open trade (for no specific players) and then be added to a group for players who have trade offers. When a player wants to view trade offers, the API will get all the players in that group and access their trade ID's (stored somewhere - player data, group data?).
Would this be the best way? Or is there a better alternative that isn't as "hacky". Also what would be the best way to store a player's trade ID's which could then be accessed with that player's ID.
