Commanding respect

I recently caught the end of Cecil B DeMille's classic film The Ten Commandments - the one with Charlton Heston marching around, leading his people towards the Promised Land.

Made in 1956 this film is epic in every way. But something niggled. This was pre-decimal, so why not twelve commandments?

If you follow my train of thought, albeit a little wind up train that possibly has a screw loose, you know it makes sense.

So what would those missing commandments order?

In the 21st century we have our own needs for guidance. Here are my suggestions:

Thou shall not swear at the computer
Thou shall not press delete without first backing up

What would you command?
