CWL conference delayed to February 8-10th, 2021


We are moving the CWL mini-conference to be four weeks later as our original schedule was too ambitious. This will also give you additional time to prepare your presentation. For those who indicated that they would be happy to give multiple presentations or were okay with multiple lengths of presentations we will be contacting you shortly to confirm the details.

I’ve updated the schedule above

We would also welcome assistance with the event itself. Check out to see our to-do list and to offer suggestions and assistance.

Best wishes for the new year!
