Event control, steward voice rooms and a text to every ticket holder
Stewards talk in a voice room for their zone, the crowd joins a text list by scanning posters at the gates and campsites, and event control sees every report and reply on one board.

A greenfield site has no PA in every corner
The arena is loud, the campsites are a long walk from control, and the crowd changes every day. whoot. reaches people on the phones they already carry: voice rooms for your teams, and a text for anyone who has joined the list.
Everything that is said and sent is recorded, so the debrief can work from the record instead of from memory.
Typical situations
Severe weather
Lightning is forecast. Hold the stages, text the arena and the campsites to tell people where to shelter, and stand the alert down when the storm has passed.
Crowd pressure at the front
The pit team call it in on voice, the public report it by text, and event control sees both reports come together on the Monitoring board before anything is declared.
A lost child
A description goes to every steward's phone at once. Supervisors report each area once it has been searched, and the record shows who looked where.
Event control sees what is happening across the site
The Monitoring board follows every voice room and every public report at once and keeps a live situation summary: what is happening, what control should be concerned about, and what nobody yet knows.
- Activity in each voice room, minute by minute
- A signal when a keyword or a surge in activity appears
- Raise an issue or declare an alert from the board
