Shared Workspaces
A shared workspace is a copy of an existing domain that allows multiple users to work on it simultaneously. User commits and updates are not required to see changes within a shared workspace. Use shared workspaces to allow users who have their own login to share their changes with other users who have their own login. For example, Users A and B are both working in a shared workspace. When User A does a build, that build contains the changes from both Users A and B. By default, all users have access to a shared workspace.
