I have noticed how much commerce amongst players is becoming more and more popular, especially recently. I noticed how advertising trading offers in global chat can bother some people and they express their displeasure. So, I thought it would be nice to have a chat separate from global that allows players to advertise their offers and deals as much as they please without bothering players that did not want to see it, so I thought of Trade Chat.
Trade Chat would be seen by all players of the server, allowing players' advertising to reach as many people as possible to see if anyone is interested. However, unlike Global Chat, Trade Chat could be disabled: players could enter a command (something like /tc) to toggle whether the chat is visible to them or not. This way, players that are interested in viewing these deals can choose to view them, and others, choose not to. I think Trade Chat should be enabled for all players that connect to the server, that best eliminates incidents where players forget to enable it if they disabled it temporarily for whatever reason.
I believe this is a feature that would be very useful and satisfy all players. It would be an effective chat filter and would give players the freedom to be as expressive as wish to be when trading.
