 - Users most affected by errors
 
+### Issues
 Choosing "Issues" allows you to query issue properties, such as `is:unresolved` or event properties such as `error.handled:0`, and to sort by issue fields such as `First Seen`. When searching on event properties, the search will return any issue that has one or more events matching the supplied event filters. Choose this data set if you want to customize a list of issues on your dashboard. Some widget examples include:
 - Issues assigned to your team
 - Most frequently occurring issues
 
 The "Issues" data set is only available in [table](#table-results) visualization widgets.

+This feature is available only if you're in the Early Adopter program. Features available to Early Adopters are still in-progress and may have bugs. We recognize the irony.
+If you’re interested in being an Early Adopter, you can turn your organization’s Early Adopter status on/off in General Settings. This will affect all users in your organization and can be turned back off just as easily.
