How to change talk slots: If you are giving a talk and would like to change your scheduled slot, contact the authors of another talk to swap, and write to the organizers only when you have a swap arrangement. You may use the Discord server to ask if anyone is willing to swap. Please try to swap with a talk from the same field, so that sessions can remain thematic and audience members don’t need to move rooms in the middle of a session.
