Thank you, this model works great already for organizers who could now confidently know they won’t have to recreate an event each time and also gives the safety that people people won’t subscribe in advance because organizers can always cancel an event for certain reasons.
The create in advance model I suggested also works for many cases and would complement your event successor model.
By the way for event successor mode PR :
1 ° Do people who subscribe to the new event still get to know that the topic/event is part of recurring event serie like the original event/topic is?
2° Is your auto invite original guest to the event an opt out/in option? I say this because a future event is not necessarily an event that you want to always promote to the guests since you already promoted the event and its serie once to them via the first event.
