Title, date, optional location, optional capacity, optional fee. Public signup page generates automatically with a clean URL. ### Time-slot signups Each event can be a single slot or multiple time-slot shifts (e.g., volunteer shifts across a 6-hour event day). Per-slot capacity and waitlists are independent. ### Automatic reminders Set lead time once during event creation (e.g., 24 hours, 48 hours, custom). Reminders ship automatically to every registered attendee. No manual sending. ### Capacity and waitlists Set capacity per event or per slot. When a slot fills, the next signup joins the waitlist. When someone cancels, the next waitlisted attendee is auto-promoted and notified. ### Stripe payment collection Connect Stripe once. Charge per signup, per slot, or per series. Money flows directly to your Stripe account minus the standard 2.9% + $0.30 processing fee. No middleman, no platform fee. ### QR check-in Every confirmed signup includes a QR code. At the event, open the dashboard on any phone and scan codes for instant attendance tracking. Exportable as CSV. ### Collaborator management Invite co-organizers with their email. They can manage the event alongside you. ### Attendee messaging Broadcast updates to all registered attendees from the event dashboard. ### Gap alerts For shift-based events, I'm In! flags slots that are dangerously underbooked early enough to take action. ### Calendar download Confirmed attendees can download an .ics file for the event, which adds it to Google Calendar, Apple Calendar, or Outlook. ### CSV export Export the full attendee list, dues paid, attendance records, and event metadata at any time. --- ## Privacy and Data I'm In! does not show third-party ads on signup pages.
