This meeting is starting in 10 minutes. This meeting is sure to be
exciting. Perhaps not as exciting as the INCITS/C++ meeting was earlier
today (you don't really want to know; suffice it to say that Zoom links
that contain an embedded password should never be publicly accessible),
but exciting just the same!
