The Yell System
If you have any questions/suggestions/remarks you want to tell the admin, but if nobody is online you can sent a Yell. This is a message which only the Emperors and FleetCommanders can read.
To do this just press y at a short prompt. A little menu will pop up, and the only thing you have to do now is pressing y two more times. The rest goes the same as making a post, or leaving somebody a mail.
Keep in mind that Yells are only for serious things. Don't abuse the possibility of sending Yells as it will scroll away the serious Yells. If you decide to abuse this function then the admin will see herself forced to take appropriate actions.
