Here's the poll for possible dates
<https://doodle.com/poll/cde4pr3nhgf89kgp?utm_source=poll&utm_medium=link>
for the F2F meeting.

The poll only has the start date of the meeting.  As before, the meeting
will be two hours per day, 4 days per week, lasting 2 weeks.  Please take
this into account when considering what works for you.  (The week of May
24-31 doesn't work because May 31 is Memorial Day and a corp holiday.)
