While there are various project settings that the Administrator user can configure, there are a couple that are worth setting up when you first start using Consequence.
Go to https://consequence.app/settings/global (if you have an Enterprise account, it will be https://[your-subdomain].consequence.app/settings/global)
If set, this will require all registered users in your Consequence instance to have email addresses within one of the specified email domains (e.g. yourstudio.com). This provides additional security by ensuring that all your users have active email addresses within your organization.
