The Status column indicates the current status of each Researcher.
Newly registered researchers automatically became Not approved. This status can be changed (after checking all necessary data) simply by hitting the "Not approved" button. The new status will be "Approved". (Approved status can be changed back to not approved by hitting the button again.)
Approved Researchers can be in Active or Not Active status. Note: Only Approved Researchers' status can be activated, and only Researchers with Active status can have requests!
