As an admin, to see who has completed tasks log in to ethicalangel.com and navigate to the 'Dashboard' page from the drop down menu seen in the top right here:
If you would like to see a full report of Angels working on projects, then navigate to your profile in the top right and open up the menu by clicking on your profile picture:
 
You can then select Organisation Members, which will take you through to the page you see below:
You can then simply download a CSV file showing Angels currently working on projects as well as completed projects.
