Enhancement: "respond-by" date

[Axel-Naumann]

When scheduling events we need people to respond by a certain time to be able to organize things. How much time is needed depends on the event type - might have to book a room, or just send out an email with a Zoom link - so this should be configurable per event. It could probably be defaulted to the first time option -24h.

For additional motivation, a follow-up enhancement suggestion will be:

Thanks for adding this wonderful option for setting the "respond-by" date for a Newdle! Now that we have it, could Newdle remind participants to fill in the Newdle, say 24h before the respond-by date, for those that didn't respond yet? It would be so much nicer if a computer did it, reliably, instead of me, unreliably!

😄

Thanks for considering!

Hm, to me it feels like the kind of thing one may want to simple send as extra context instead of making it structured metadata. So I'd rather have a freetext field where you can add a message to be included in the invitation mail...
