I think we should have a auction on the server. It would stop the constant spam in chat. "Selling firestone message me!" Or "Buy a Snorlax so message me if you have one" It would be epic if Pokémon could be auctioned too. But even if it was only possible for objects to be auctioned it would be really helpful for players and a good way to get rid of their objects. I spoke to a few gym leaders about it and they said they thought it was a good idea. So I would ask that you take this idea into consideration :)
P.s Well done on 50,000 members!!
