There are 2 supported user roles that access the Venue Editor:

An Event Manager is someone who has access to the GEVME Virtual backend and is responsible for setting up and configuring the virtual event.

Typically, when you are logged in to GEVME Venue Builder, you are a Manager of that project by default.

There can be multiple managers to a single project.

A Sponsor is a user that is given access to an event under the Sponsorship module:

Once a Company for a sponsor is created, users can be created and assigned to the company. These users all have the Sponsor user role. Sponsors can access the Venue Editor to manage their "booths" (effectively LivePages).
