Apparently, there is no multi-player online game for single users of Evolver (I guess as opposed to schools). He just signed in on the online vs. offline part of the first screen. I also have parental controls on DS's side of the computer, but I just realized he played on my side today. So far, it's been a review of prior EPGY and Aleks, but moving forward, I think we'll have to use the instructional modules.
