My mother is across the country trying to learn how to use a computer. I've been trying to help over the phone but so far haven't made much progress. I've heard that Leopard can screen share and I thought this would be a great way to show her the VERY basics of computers (like email) what is the easiest way to set this up? I'm running Mac OSX Leopard and she's on a Microsoft Vista computer. If possible i'd like to do it without having to get on a plane. What is required on her end?
