Messages are the in-game method of communication between players. The Write Message icon appears in many places in OGame and clicking it will open a dialogue box, in which you can write your messages. Some places the icon appears are:

Messages cannot contain insults/profanity and must be in English. Each message received has a report insult check box at the bottom.

Circular Messages may also be sent within your alliance.

All messages can be viewed by the Game Operator.
