Permissions for users in an account can be changed in the VirBELA app by anyone with Admin privileges.
Navigate to app.virbela.com and sign in.
Locate the user whose permissions you would like to change and, under "Membership," click the "View" button.
In the window that pops up, click the Role (in this example, the word "Member").
The role will become a dropdown menu, giving you various ranks to choose from.
A world of caution: assigning permissions to your users is a lot like giving out keys to your office. Most people need only access the offices (member), while some may need access to the tools to help orchestrate operations (moderator), and a select few have full access (admin), opening the door to view personally identifiable information and make changes to user statistics in app.virbela.com.
