If you need to share your event website with someone else, you have a few options:
Add a Collaborator: To add a collaborator or collaborators to your account, you will need to upgrade to an Enterprise account. Once upgraded, click on the Collaborators icon and add your collaborators' emails.
Publish, but Password Protect: Add a password to your event website and then publish your website. Then, you can share the URL of your event website. Once you've received feedback, feel free to remove the password and share widely.
Create a Shared Login: Choose a general email address and password and share login credentials with your planning team.
