You can enable your partners to add events to your calendar by following these steps:
Login to the PeopleVine Control Panel and click on Directory
Find the company you want to assign this access to and click edit
Select the permissions you want to include
Once you save the profile, the user will have access to these permissions on their next login. Once they arrive at the main screen for businesses, they will see the option to add events or you can link them directly to /business/menu/event/create.
