Reminder: MathML core meeting today

Apologies for the late reminder. We have the meeting today at the standard
time (11am Pacific, 8pm Central European).

We may have some special guests (HTML/CSS experts) from the hackfest join
in. The agenda includes a link from Fred's talk this morning discussing the
current state of Igalia's implementation and what needs to be done to get
it into Chrome.

The agenda is at:
