hi at home i have an iMac that i need to access from my MacBook Pro while in the office. i have a MobileMe account and am thinking of turning on the "back to my mac" functionality. i've read a few things about this function that make me hesitate, that basically it makes your mac accessible to anybody if not properly set up, etc, etc… what do i need to do in order to make back to my mac work without running the risk of having my files stolen? i really appreciate a few tips! thanks, alexandre 17" 2.33ghz ic2d macbook pro / 2.0gb / 160gb / X.6.1 24" 2.33ghz ic2d imac / 3.0gb / 1tb / X.6.1 2.0ghz ic2d mac mini / 4.0gb / 500gb / X.6.1 iphone 3G / white / 16gb …and a few iPods.
