For new members, because when one came here for the first time & want to know how to steer the RE, it can be confusing to find the manual about it on the board "Missions" (besides, some steering manuals go as a chapter in the Mission Editor manual) when he's not interested in missions or haven't got any questions about them yet.
So it'd be like Tutorials > "How to contrlol..." > How to control the Red Eagle/Ocean Star/hovercraft/azimuth thruster on JJ/Container Crane...
