For any given organization, you can have up to four logins/ "User IDs." On average, most stations tend to have at least two staff members trained and registered with User IDs, though some stations simply have everyone use a single ID.
Other notes:
- If there are multiple production units, each production unit can have an EIDR organization ID (known as "Party ID"s).
- For stations that just acquire content, you will only need a single EIDR organization, or Party ID.
