Title pretty much says it all, but the spamming at the CS is getting really annoying. A possible platinum price decrease for auction slots might encourage players to buy them and thus, reduce the need for them to constantly shout out what theyre selling. If a different suggestion is needed, allowing players to setup a bazaar which is represented with an icon next to their name (much like a guild) would alert players that they are selling something, and allow them to browse directly off the player. I think that bottle necking the ability to sell more than one item at a time is in turn causing the chat log to flood.

Another suggestion: create "tabs" on the chat window for the immediate area chat, guild chat, and private chat. This would prevent the immediate area from flooding private messages and guild chat out of the window. When you select a tab (i.e: guild), tapping on the chat window will automatically default to sending messages to that channel, thus preventing the need to type "/g" before your message. This will allow quicker communication and less mishaps when attempting to chat.
