Can Slack notify me when someone comes online?

No, Slack does not have a built-in feature to notify you when someone comes online.

However, there are a few workarounds you can consider if you need to know when a specific person is available.

1. Custom Status Updates:

   • You can ask your team members to update their status when they come online. For example, they can set a status like "Available" or "Online" when they start their workday.
   • You can then check their status manually to see if they are online.

2. Direct Messages:

   • Send a direct message to the person you want to reach. If they are online, they will likely respond quickly.
   • This method is not automatic, but it can be effective for immediate communication.

3. Third-Party Integrations:

   • Some third-party apps and bots e.g. SpyBot can be integrated with Slack to provide more advanced notifications and monitoring features.
   • You can explore the Slack App Directory to find tools that might offer the functionality you need.

4. Custom Bots:

   • If you have programming skills or access to a developer, you can create a custom bot using Slack's API.
   • This bot can be programmed to monitor user activity and send notifications when someone comes online.

While these methods are not as straightforward as a built-in notification feature, they can help you stay informed about your team members' availability.
