We have created a new user group.
Should this new user group has default minimum rights or has this new user group no right
defined at all and they have to be defined ?
Is there a sort of cascade of rights : an anonymous become "user autoconfirmed",
and then "user emailconfirmed" with default rights of "user" group:
edit, move, etc ... A user defined as belonging to a "incubators" group by
administrator in "user right management" page (in special page), will have
"user" group rights + "incubators" rights ?
As a result, the right "move" from a namespace-one to an other namespace-two, is
not allowed to the user who became "incubators", when "incubators"
group has the right to "play" in the namespace.
We did this creation of new user group across the definition of a new custom namespace:
$wgNamespaceProtection[NS_INCUB] = array( 'incub-edit' ); # right
'incub-edit" is required to "play" in INCUB namespace
$wgGroupPermissions['incubators']['incub-edit'] = true; #
"incubators" has "incub-edit" right which give the right to
"play" in INCUB space
