General MathML meeting on Tuesday (8 Oct)

We have a general meeting on Tuesday to discuss Sam and David's
contributions for semantics in presentation MathML. For links, please see
the meeting agenda at
https://github.com/mathml-refresh/mathml/issues/91#issuecomment-539119949.
Although there won't be a test on all 1,500 entries from Sam (or the 45
from David F), I highly recommend looking over their work before the
meeting.

The call is at 8am Pacific, 11 am Eastern, and 5pm Central European Time.
