You may create ("embed") a shared Workspace inside a Workspace using 
or 
or [Public Access]. You may transfer ([Cut] and [Drop]) a Workspace into another one or 
it from a higher-level Workspace and 
it somewhere else in your 
Folder.
The BSCW Group (the members) of the higher-level Workspace is automatically added to -- or removed from -- the BSCW Group (the members) of the embedded Workspace: Embedding a Workspace in another one, or removing a Workspace from another one, automatically changes the membership of the Workspace that you transfer. Remember to check carefully whether these automatic changes are what you intented and correct the membership (see section 4.5) and the access rights (see section 4.7), if necessary.
