Any DonationMatch user can add a "Viewer" to a donor company or nonprofit profile; this type of user is treated like a cc: email address to receive the same email notifications as the main account with regards to offers, requests, and reminders. Viewers will NOT receive password reset emails or messages pertaining to the administration of the account.
Another feature is the ability to log in and see this activity, but not manage or respond to it.
The main account is the only login that can access and act upon events and donations.
