How does it work?

When you click the tab, you can enter the number of commands you wish to send and the desired time gap. The extension is capable to send any number of commands in a given interval and is thus more reliable than the normal game updates.

Note that the extension is not capable to send messages from one player to another, nor from one server to another.

If you find that the messages are not arriving to you, please make sure that your client is connected to the server. 

However, it is not responsible for the content of the messages. The same holds for the extension.

You can find the Tribal Wars Train extension on the Chrome store.
