What is a Workspace?
A Workspace is a place where the magic happens! :)
You get your own Workspace when you create an account. You invite people to your Workspace, create and work on projects with your team there.
However, when you get an invitation to join Casual, you join the Workspace of the person who invited you.
Each Workspace requires a Subscription. Your account is active during the 14-day trial period but when the trial ends you need to subscribe to Casual if you want to use it.
Once you subscribe, you get some storage space, and a certain number of users gain access to your Workspace. That number depends on your pricing plan.
