The World Café method is a collaborative dialogue format for large groups and part of the Art of Hosting method universe.
Participants have a collective, progressive conversation by moving from table to table in overall three rounds. Typically, each round starts with a question to leverage the conversation to the next level.
This template creates a virtual Café setting, allowing participants to pick the "table" (= call) they want to join. It needs to be complemented by a call setup which allows several parallel calls - 1 main call and as many calls as you have tables. It's currently mapped for ca. 40 participants (10 tables) and can easily adjusted by adding or removing tables.
