FAQs
Frequently Asked Questions about the Cavrnus Collab Viewer Template (CVT).
A Cavrnus Space is where multiuser collaboration happens. It's like a session, but it is persistent and always available with complete history. You can connect to multiple spaces from the same application.
Your Cavrnus domain (example.cavrn.us) is the unique custom URL where all of your spaces and users are hosted. If you're not already part of a domain, you will be required to create one when you sign up for Cavrnus.
You only need one domain for your entire organization, and you can add unlimited team members within that domain from your Management Console.
