Can I get a list of completed items that were done by others. I am trying to use this in a team environment and it would be nice to see what the team has accomplished. Any advise for me?
Unfortunately, that's not possible, you can't see which tasks were completed by whom, at least not on any fixed list. You can of course see if someone completed a task you've assigned to them in the alerts section and get notified about it via email or push notification.
