If you want to see an overview of all the workspaces you're a part of, who the admin is, and how many members it has, you're in luck! Find it all on the 'Manage Workspaces' page.
To get there:
Click on your avatar in the bottom left
Select 'My Workspaces'
If you're the admin of a workspace, you'll have the additional option to 'Manage Workspace'.
- From that page, you'll be able to adjust billing settings, adjust the number of memberships, member permissions, and invitations
If you want to leave a workspace, just click on the 'Leave Workspace' button
Now get out there and create cool stuff!
