[pmwiki-users] groups for all wikis in a farm

[nexyufuli evo]

hi list
is it somhow possible to define  groups in a filed, that they are 
accessible with wikilinks for all fields?
I currently work on a farm, where every client has he's own wiki. Put I 
would like to define some groups in the main wiki. That sould be 
accessibel for all fields.

Also it would be nice, if the admins of a filed could decide, that they 
want make a specific group accesible for alle other fields.

How could I do that?
