Set your status in slack (slackhq.com)

This was a good idea, but people use them largely for whimsical purposes and they add a lot of visual noise. There isn't an option to disable them, but if you use Slack in a browser, you can do this in a custom stylesheet:

    .feature_user_custom_status .current_status,
    .feature_user_custom_status .message_current_status {
      display: none !important;
    }
