My boyfriends going off to college and I'm still a senior at high school. we want to video chat a lot to keep close. I have a mac and he has windows vista. Does anyone know of a good video chatting system to download that is completely free and safe. Something with good quality and maybe some fun features if it exists but also something that won't slow either of our laptops down and that will work good with both of our systems. THANK YOU so much in advance!
