Inviting communities to member groups and vice versa
In the previous section, we have
seen that communities may be invited as members to another community, thus
making them subcommunities of this community. In 4.5.3 Member
groups it is described how a whole member group of a workspace may be
invited as member to another workspace. As mechanism for these actions
we use the address book which may contain entries for communities and member
groups, and which in turn may be selected in the ‘Invite Member’ form
using the ‘Choose from my address book’ option (also see 4.5.1.2 Membership administration). You may add
communities to your address book, whenever communities appear in a listing
(‘Other Communities’ or the members’ page of a workspace with a community as
member), by ticking the check boxes in front of the community entries and
selecting 
in the multi-selection toolbar.
Note that communities that you create yourself are automatically added
to your address book.
We may now ask whether it is possible to invite communities to member groups of workspaces, and vice versa to invite member groups to communities. The answer to this question is generally yes, but the effects of these actions are not what could be expected at first sight.
