The way we price our plans is based on the amount of active users who interact with your feedback portal. This also includes via integrations like Intercom.
This means we count anyone that comments, votes, or submits a piece of feedback as an active user. If someone signups but doesn't do anything, they are not counted. If a user is created via our SSO integration, and they don't do anything, they are not counted.
To see all active users for a project, just head over to the users tab within Suggested and you'll be able to see a list of users who have interacted with your project. You'll be able to see what comments they've made, the feedback they've voted on, and any feedback that they've created.
