At present, the plan is to have all materials posted by Oct 19. If there is interest and we have the ability to do so, we will hold live streaming events from Oct 19-23. Ideally, these events would be coordinated so that our international audience can participate.

We would also like to suggest that those submitting a document also consider creating a video presentation. Ideally, we wish to include links to the videos and will post them on a website. The videos should be no longer than 10 min. As well, all videos should be uploaded to YouTube to ensure consistency. However, we do understand if there are issues within any particular region. Links to videos should be sent to the conference coordinators by October 10.

Live Events: If you plan to host a local live session (pandemic conditions permitting), we can coordinate your session with a questions and answer period. Again, you will need to send us the appropriate link well in advance (see above deadlines).

While the committee does not endorse any software, please be aware that there are a number of freely accessible ‘desktop recording’ software is available. Some basic ideas are included in the appendix (see below).
