ARRC has been offering weekly office hours since March 1, 2019. The office hours are hosted by David Bowman, Senior Advisor at the Board of Governors of the Federal Reserve, every Fri afternoon 2-3pm, and open to the public. I listened in to the 3rd session last Fri, and found it quite informative.
To join the office hours, call 1-855-377-2663 for US callers, and +1 972-885-3168 for international callers. The participant code is 09823427.
