Never mind the later in the week part, I had 2 samples of group shot images that could be used to test Microsoft's Group Shot application.
Bottom line: this utility is awesome!
I am sure some people can do all of this with Photoshop, but Group Shot makes it possible for everyone to do it.
Here are my examples
Basic instructions for using Group Shot can be found here.
Thank you Microsoft! Now can we have a OS/X version?
