Steve, doing a personal practice session from home for invited guests would be useful, and for me a 40 min time limit would be fine. But it would be in preparation for presenting via someone else's zoom channel - much as Hamish describes re "Ukes for Unicef". I think only the host can screen share. I don't know what facility the main host gives to the presenter. Steve, I think you have done an online paper for the ballad forum? I suppose that would be similar.
