Edge cases
The odd situations, and what happens in each.
Two people, one last spot
- If two people grab the last spot at the same moment, one gets it and the other is told it just filled.
- If you add spots while people are signing up, their page may take a moment to catch up.
- The same email can't sign up for the same slot twice, but it can take a different slot.
Multi-day events
- Each date is its own occurrence. When you change one day's time, check you're editing the right date.
- Switching between single-day and multi-day after people have signed up can leave signups on the wrong date. Check the list and email people if you do it.
Time zones and calendars
- A daylight saving change can shift the time people in other regions see. Check the calendar link if your event is near one.
- .ics files and Google Calendar links are written in UTC, so each calendar app shows them in its own local time.
Emails
- Confirmations and reminders can land in spam. Ask people to check there and mark them as not spam.
- If nobody has signed up yet, sending a reminder tells you so instead of sending nothing quietly.
Spam protection and rate limits
- Some steps ask for a quick robot check (Cloudflare Turnstile).
- Lots of submissions from one connection in a short time get “Too many requests” and a note on when to try again.
Editing after you share
Tip: for anything that really matters, stop changing slots a day or two out, and email everyone once with the final plan.
