First and foremost, I apologise if this is in the wrong place. I received my first Mac this morning and have had no problems with it, I'm enjoying learning a new OS. I have a couple of questions though and I'm hoping somebody will be kind enough to help. 1) I had a fire break out in my room a couple of years back and ever since I have turned my electronical devices off at the mains during the night, if I was to do this nightly with my mac, i.e. shut it down and then take the plugs out - would it do any harm? 2) I have downloaded Adium and then Messenger for Mac and both times tried to send a friend a link from imageshack, which I had always been able to do on my windows machine. I was just wondering what is the problem with sending links? Is this common? Thanks to anyone that helps.
