Can I filter by permission levels for the Organization?

As an Organization Manager you are able to filter the Organization Staff list by permissions. Under the General Organization Filters, you will find a Permissions option that will allow you to filter down to users that either have or do not have one or any of the permissions levels.

read only filters

Using this filter can help make sure that any actions being taken are only including users with the correct permission level. For example, if you are trying to send a message to al your staff/volunteers and not any of the admins, then you can filter the Organization staff list to only show Basic Users.
