How early should the signup page be live?
Before the first piece of promotion, which for most sessions means days rather than hours. Attention arrives at odd times, and a page that is ready turns a curious click into a registered name. Set up once, then promote without worry.
What seat number should I choose?
The smallest of these: what your video platform truly holds, what your speakers can handle in discussion, and what you can follow up on afterwards. A list capped at a number you can honour beats a big number that turns into apologies.
Can I see who has signed up while promotion is running?
Yes. The registrant list updates as replies come in, so the effect of each post is visible within the hour. That is what makes the timing decisions possible: push more, stop, or mention that seats are filling.
Do reminders need to mention the time zone?
Every reminder should carry the time and the zone together. A reminder written in the host's local hour quietly excludes half the list, and a wrong time in a reminder is worse than no reminder at all.
What if nobody signs up in the first days?
A page that is ready costs you nothing while you wait, and an early list is a useful signal for a second push. With the capacity in place, promotion is a decision you can make while the list sits open in the dashboard.
