Access to the Shared Place
<usergroup>syracuse</usergroup>
<usergroup>boston</usergroup>
<usergroup>washington</usergroup>
This fragment declares that only members of the groups: syracuse, boston, and washington can access the shared place.
The declaration uses the ‘place’ tag, therefore the access restriction applies to the whole place (chat and viewer objects). However, it is possible to define separate settings for the specific objects.
