In view of ongoing travel advisories and physical distancing protocols related to COVID-19, all in-person BIRS-CMO workshops scheduled for this year 2020 in Oaxaca, will unfortunately be cancelled.

At this time, we offer the organizers the option of proceeding virtually, with BIRS support, to have the meetings online. BIRS will take care of archiving and broadcasting the participants' talks online.

The offer of a virtual workshop does not replace the original opportunity to conduct an in-person workshop in the future. For the time being, we invite the organizers to consider the virtual workshop as an interim meeting platform.

If organizers decide to run their workshop online, we ask them to check this link: http://www.birs.ca/organizers/online-birs-meetings to see how BIRS can help in setting it up.

The postponed and cancelled workshops from 2020 at CMO-Oaxaca will be considered to run in 2022 and beyond. We ask their organizers to update their proposals. The deadline for proposal submission is Friday, October 2, 2020.

All proposal submissions must be made using the online submission form at https://www.birs.ca/proposals.

Thank you for your understanding. I wish all of you good health in the days ahead.
