Access to the Shared Place
<user_group>syracuse</user_group>
<user_group>boston</user_group>
<user_group>washington</user_group>
This fragment declares that only members of the groups: syracuse, boston, and washington can access the shared place.
The declaration uses the ‘place_access’ 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.
