We posted this question on XAware.org and received the responses shown below.  24.5% of those who have responded have said, "My role is not on this list".  I am a bit surprised that we couldn't come up with a more inclusive list of choices, and somewhat curious about what we missed.  Please help me out here.  If your roll is not on the list, or if you think youknow what we missed, please add a comment to this post to tell us.    THANKS!
