Records can be marked as Inactive if they are not actively particpating with an organization.
Select the Biographical Information tab
Click the Mark inactive button
Note: You can delete records from your database to make reports and queries cleaner and more accurate, but when a record is deleted, the information is unrecoverable. Marking a record as inactive is an alternative to deleting it from your database. In this way, you can retain the record's information, but it doesn't show up in queries or reports by default.
