Can Graph tell me when users are online?Absolutely. We have 2 plugins that support user presence. The first is our Users plugin. This delivers features including presence, session management, user authentication and user info management.
You can also accomplish this via our Presence plugin. This enables you to ping a service when the user does something and define how long a user has been inactive before they're considered offline.
Both are instantly available for your projects and can be integrated in as quickly as 5 minutes.
