Preview of October Virtual Interim slide deck

Given that we did not schedule an August Virtual Interim, we had an abundance of material submitted for the September 20 virtual interim (today).

Rather than trying to squeeze everything in and running out of time, we are going to schedule an October virtual interim in addition to the upcoming TPAC meetings.

The draft slide deck for the October Virtual Interim (including slides we won't be able to get to today) is here:
