so you can congradulate the winner or if you won, you can say to everyone "great auction battle everyone!" or "that was fun everyone!". that would kinda relieve tension between players if people can show good manners after an auction.

i know you guys can say "oh theres already a chat function in the game" well what if there was 5-6 different participants in the auction, you cant remember them all and how are you gonna send a seperate message to them all even if you did. this simplifies things.
