Over a period of three days (15th - 17th September 2020), we organised and hosted an entirely-virtual symposium on "The Future of Meetings" (hereafter, TFOM). This report collects our findings and observations over the entire period from conceiving the symposium to the post-event phase. Our goal is to share the many lessons we learned in putting TFOM together, as well as our recommendations for best practice for interactions (especially of a virtual kind) going forward. We treated this symposium as a chance to experiment with many different approaches (both technical and sociological) to discover what worked best and where improvement is needed. We hope this document is useful for those considering future ways of optimising virtual/digital interactions.
