Once you have logged into the Jisc Community and launched the JCS portal you can view all certificates which have been requested by your organisation. Do view these certificates, click on the down arrow next to the 'Account' tab and select 'View All Certificates', as shown below:

When all certificates are displayed, you can click on the spanner icon on the far right of each certificate to view more information about that certificate request, including downloading it.

It is also possible to create a spreadsheet of all your organisation's certificates by using the "CSV" button
