  • The phone bridge can only handle 100 simultaneous connections, and we have far more than 100 participants, so the phone bridge ISN'T the preferred connection method.
  • We'll be on the phone bridge but will have our volume turned down, so we won't be able to hear you.

In case of a failure during a live presentation:
 
Please try to get back in for a few minutes, then switch to another video source, or, in the worst case, to the phone bridge.

If you cannot get in via your preferred mechanism, please send e-mail to:
