If I was not active on my computer, it would automatically log me out after a few minutes, if I was in a meeting, the bathroom, talking to someone, on a long phone call, proofreadin, etc. Then when I came back I would log back on again. So, if I was there but NOT on my computer, I could say I was there, just not on my computer. But if I was ON my computer and actively working, there is not way I could say I was NOT there. IMO. MOO. so if there is activity that she was on her computer, pretty good indication she was there. Just depends on the times of her emails and activity on her computer, what this will show. IMO. MOO.
