Users become members of a workspace only by being invited by the manager or another member authorized to do so.
If you are a registered user of a BSCW server and have been invited to a new workspace, you will at least recognize this by the fact that this new workspace appears marked with an orange bar in your personal workspace ('home folder'). New members are additionally informed by an invitation message if the corresponding option in the 'Add member' form has been activated.
In your regular email report on activities in your work areas, you will also be informed about invitations to work areas from the previous day.
Your personal workspace ('home folder') is the default
position BSCW uses for new shared workspaces. You may drag and drop such a new
shared workspace or use the context menu to 
and it somewhere in your personal
folder hierarchy. This moving of the whole workspace is not visible for
the other members, unlike moving objects within the workspace. If you
move the new workspace into an already existing workspace, it becomes part of
this workspace and the members of the parent workspace (its member group) become
members of the new workspace (see also 5.1.4.2 Embedding one workspace into another).
If you are invited to a workspace and you are not yet a registered user, you will receive an invitation message along with a request to register. After registration, the workspace you have been invited to appears in your personal workspace ('home folder').
BSCW does not offer a special feature to decline an invitation to a workspace. You may terminate your membership in two ways:
•You remove yourself from the member group by
o click on the menu 
and select Manage
Members tü display the members page of the workspace, and
o
in the
context menu of your own entry.
•You delete the workspace, i.e. you remove it and then delete it in the Trash. Simple removal is not enough: even if the workspace is in your Trash, you still remain a member.
To gain access to the workspace again after leaving, you must ask another member to invite you back. It is not possible to invite yourself to someone else's workspace.
