World Trade Channel

Enable you to see trade channel even you are not in a city
This Addon will enable you to see trade channel [2. Trade] even you are not in a city. The function will automatically enable when you when you leave a "Trade - City" channel. You can't talk in the "Remote" trade channel, but you can whisper to anyone just by click their names.

Install
Like other Addons, just put it under folder "World of Warcraft\Interface\AddOns". You do not need to do any configuration!

Uninstall
Just disable or remove the Addon, we use no configuration file or data file.

Usage
Commands Prefix: /wtc or /worldtradechannel
ENABLE: on, start, enable ...
DISABLE: off, stop, disable ...
Sample: /wtc off

Mechanism
This Addon will use a hidden channel to forward messages from city. So the Addon may not work if only one person using it in your realm.
We promises to keep this Addon OPEN (using MIT License) and ACTIVE.
We hope more people will use it.

Q&A
Q: Will I see duplicate messages in trade channel?
A: NOP
Detail: We use a small cache to make sure you will see message only once. If you in city, the Addon will not show anything. If you are not, it will show message only once in the "fake" trade channel. We also use this cache to prevent message from "duplicate send".

Q: Will I receive junk messages when using it?
A: You will only receive messages from trade channel.
Detail: We use a validation to block "fake" messages. The hidden channel is managed by Addon, someone try to send messages directly to this channel will not show.

Q: Will I generate more Addon traffic?
A: YES, but very very few, << 0.2 KB/s, and usually less than 10 B/S.
Detail: We use a mechanism to make sure each message will be forward only once. On the worst case (you are so bad lucky to be the forwarder of all messages and you forward 1 message each second and all messages have max character count), you will only generate about 0.2 KB/s traffic. And we test it all day only generate 10 B/S on average in a very active realm.

Future
We will keep it simple and stable.

We hope there will be an official World Trade Channel
