You are not logged in but can still report alerts. However, we suggest that you login:

1. Your alert will get approved more likely because alerts from anonymous users are regarded with higher scepticism
2. You can declare alerts as time-critical which will get it sent out faster to community members
3. You’ll earn points for reporting alerts which will get you various privileges – for example, you’ll be able to send out alerts faster to the community because they won’t have to be reviewed
