Reminder: MathML meeting on Thursday

[I thought I had sent this, but I guess google is not yet smart enough to
click "send" by itself :-)]

We meet at our standard time on Thursday, 10am Pacific, 1pm Eastern, 7pm
Central European Time.

The meeting details were sent to the W3C members-only "member-math" mailing
list <https://lists.w3.org/Archives/Member/member-math/2021May/0000.html>
for the group. The regulars for this group should have the meeting details
in their calendars.
