All current members of a Workspace form a BSCW group called 'Members of <Workspace name>'. Vice versa, any BSCW group has a shared Workspace associated with it.
BSCW groups are a useful tool for the administration of Workspace membership or shared mailing lists and for the management of access rights. In particular, a BSCW group lets you store and update the assignment of persons to a task in a single place and use this information in many places (for instance for assigning access rights) with an automatic update based on the changes of membership in the BSCW group.
(1) the local heads of the subprojects in each participating research center,
(2) - (4) three groups of researchers, e. g. clustered by discipline,
(5) the local sys admins,
(6) the local accountants responsible for the subprojects.
Obviously, people may be members of more than one of these basic Workspaces, e. g. a head of a subproject or a sys admin might be a researcher at the same time.
to add the BSCW group formed by all the members to your Address Book.
in a way that is very convenient and at the same time offers an internal structure that would allow you to assign different access right to the different groups of members in a Workspace. (As an example, in the 'Budget control and financial reporting' Workspace the BSCW group 'heads of subprojects' might be allowed only 'read' access very easily.)
BSCW lets you retrofit this kind of structure based on BSCW groups (= Workspace membership). However, this action is for experienced users only.
to bring up the 'New group' form that lets you enter the name of the new Workspace.
to create a new Workspace (= BSCW group). The selected entries "disappear" from the list where you selected them; they are replaced by the new entry 'Members of <Workspace name>'.
to display the new Workspace's Members page. There you now find the individual entries for the members of the new BSCW group.
This Workspace will show up on the top level in the Folders of all its members.
As a side-effect of creating this BSCW group and the new Workspace with a subset of the members of the original Workspace, the original Workspace will no longer appear in its usual location in the Folder hierarchies of these members. It will now be embedded within the newly created Workspace that is located in the Folders of these members.
As you have modified other people's Folder hierarchies, you may want to contact them and advise them to move the new Workspace to some unobstrusive location, but not to delete it.
