What is a critical element to address with speakers before the event?

A critical element to address with speakers before the event is their comfort level with the chosen format. This ensures that they are well-prepared and can effectively engage with the audience, which is vital for the overall success of the presentation. When speakers feel comfortable with the technology and the interactive elements of the event, they are more likely to deliver a confident and effective presentation. This preparation can also help alleviate any anxieties they may have about presenting in a virtual environment, thereby enhancing the audience's experience.

While availability for future events, promotional materials, and duration of speaking time are all important considerations, they do not directly impact the speaker's immediate performance and effectiveness in the event format. The level of comfort with the format can influence the delivery and audience interaction, making it a priority for successful presentations.
