For those that may not be aware, Skype has released v2.0.0.6 for Mac. This version supports video on Skype, which is great. I have tried this out for video calling betweem family members on PCs and myself on my Mac, and it works great. So, if you have an iSight camera and friends/family you want to video call from your Mac, give this a try. It seems to work quite well. Visit
www.skype.com to pick it up.
As always, when I endorse a commercial product (this one is free by the way, so don't worry about that), I need to point out that I am not in any way affiliated with Skype, just a happy customer.
