In the section "Permissions" you are able to activate sub-accounts. In case you possess several accounts, those will all be able to access the same event - you just need to select the respective user in the field below. If you click on the respective user in the column "Available Items", he or she will automatically be transferred into the column " Selected Items". Repeat this process until you have selected all required users. To save the changes of permissions, click "save" at the end.
