I have talked in the past about Zoom and it's potential to host virtual Knowledge Cafés.
Having run a few small experiments, I run a fully fledged virtual Café at the end of April with 20 participants from 6 different countries.
There is no doubt in my mind now just how effective a platform Zoom is and I'll be running many more virtual Cafés and events in the future.
If you would like to be kept informed about them, please sign-up to my Virtual Café mailing list.
