I'm gonna be adding my parents 2 machines to my roster pretty soon, I doubt the two combinted will produce as my one does (they are slower machines, plus they are off alot of the time) but at elast it will add some computing action to the team.
I've got em goin now- I don't think either of them has turned in a WU yet, but they're cranking- The fact that they are only one about 5-6 hours a day means they won't produce a whole lot, but hey it's better than nothing.
