Preparation is everything - start early in having regular team meetings to collate ideas collaboratively for the event, allow for time to secure speakers and advertise the event early to engage delegates.
Communicate clearly with delegates in advance so that they understand the format of the event and how to navigate the software.
Ensure your team has a rehearsal if using the system for the first time so that they know their camera and microphones work.
Think about how best to structure your event - will it be more effective as a one-day event or over a few days like a summer school?
If possible, have a variety of speakers and workshops and think carefully about the timings of the slots. If you’ve joined IVMC you'll notice we have 4 speakers in the space of 1 hour rather than 1 person for 1 hour to keep attention and engagement up.
We believe in the power of diversity: make sure you have speakers from a full range of backgrounds.
Make sure everyone knows what they are doing, clear up as many doubts as possible before the event. Have defined roles for each individual in the team.
Consider having breaks between sessions - you will greatly appreciate a breather (and often participants will too!)
