The 2021 virtual Congress will include a mix of “hybrid” and “live” oral talks.  The format of oral talks in each Division was at the discretion of the individual Division Chairs.

A hybrid talk means that the presenter is being asked to submit a pre-recorded full presentation, which will be made available to delegates before the Congress starts.   There will also be a shorter “live” presentation scheduled during the conference where the presenter will summarize (and update) the information provided in the pre-recorded talk.  A moderated question and answer period will be included during that session.

A live talk means that the presenter will be giving their full talk during the Congress session.  Time for questions will be included.

Since sessions must keep to the schedule, all presenters are encouraged to be online and logged in to their session at least 30 minutes prior to the session start. This will allow an opportunity for presenters to introduce themselves to the session chair, and to set up and test their presentation in advance. Assistance will be available through online session moderators/support personnel.

All sessions and presentations at the Congress will be recorded and the recordings will be made available on the Underline platform shortly after.  Any presenter who does not want the recording of their talk made during Congress, or their pre-recorded submission (if applicable), to be made available outside of the Congress-delegate access period will be able to indicate this on the live speaker release form at
