In my linux migration, one of the biggest obstacles I have been facing was the lack of a reliable, free messenger allowing voice and video.
Looks like skype will solve that problem for me.
Skype has versions for linux as well as windows. Just installed the linux version; voice works fine.. Can't check out video right now as I don't have a linux compatible webcam..
Anyways, if I can get my parents to use skype too, then one major issue gets sorted out..
And as a bonus, skype allows conference calls too !
