Can you try to be less hostile. I don't think the situation calls for it.

The fact of the matter is, I have asked every person in the org for their attendance, and followed up with every person who said they couldn't make it. In the case of Networked members, I went through your ND and received this information.

I am following up on a task I was given, nobody is out to get you, it's my job to understand the reasons why people are not coming. If you don't show up to work, your boss might give you a call right?
