Type in commands: tutorial - sends a tutorial. repository{1 - 4}.read - sends contents of repository on server. repository{1 - 4}.write {contents} - writes {contents} to repository on server as long as length of {contents} is not bigger than 2048 characters.
If this does not work, the server is probably down. If the contents of the repository are inappropriate just write something else to the repository. All interactions are saved for moderation purposes.
