Manage events via Google Forms™: set a limit per session, manage the bookings, and send each attendee a ticket or a certificate.

Overview
🎯 SEAL runs a whole event out of one Google Form™: the sign-up caps itself, you manage who took a place, and everyone gets their document by email. No spreadsheet gymnastics in between.

⚙️ HOW IT WORKS
Every session, seat or time slot is an answer option with its own capacity, watched by a choice limiter of its own. Each incoming response is counted against the option it picked, and a full option leaves the form. The booking is therefore done by the form itself, and nobody can sign up for a place that is already gone.

📋 MANAGE THE BOOKINGS
See the responses your form collected. Open a single one, delete it, or copy the link that lets a participant change their own entry and send it to them. Deleting a response frees the place it occupied straight away, so a cancellation reopens the slot without you touching the limits.

🔁 RESET FOR THE NEXT ROUND
Run the same form every week? A daily or weekly reset clears the responses for you, so the next round starts on an empty sheet. It stays off until you switch it on.

📨 TICKETS, INVOICES AND CERTIFICATES
In event mode each attendee receives a ticket or an invoice; in quiz mode SEAL checks the score and sends a certificate. Pick one of the built-in templates or bring your own design.

✏️ PERSONALIZE WITH MERGE TAGS
Use placeholders to fill in the name, the department or any answer from the submission, in the document and in the mail around it.

📅 USE CASE: A COURSE WITH LIMITED SEATS
Three sessions, twenty seats each, one form. Each session drops off the list as it fills, you see who booked what, and everybody leaves with a ticket in their inbox and a certificate after the exam.

📱 SHARE VIA QR CODE
Every form can be shared instantly via a built-in QR code, in the size you need. No extra tools required.

📧 EMAIL NOTIFICATIONS
Get notified by email whenever a limit is reached, so you always know how full your event is.
