Survival's newly-temporary auction system has been recently implemented and this is to clear up any confusion about the things the plugin offers and how it works:
When issuing the command </auc help> in game chat, you will be provided with a list of commands that the plugin offers including how to start, bid, etc. ---

/bid [amount] Place a bid
