1. Unlike regular monitors which I can shut off when I'm about to sleep to ensure darkness, how do I do the same with my iMac without shutting down the actual iMac in the process? I mean, it might be processing something in the background so I dont want to suspend it, but simply switch the screen of completely. I know I can dim the screen by pressing the F1 key, but want to darken it completely.
2. Also I am just registering for mobile me for the first time along with iCloud. It is not recognising my itunes password. Should they be the same / doesnt recognise my itunes email address. I thought the Apple ID and mobile me/icloud use the same username and password?
