MAILBOX TAGS (BOZZA)
------------------------------------------------------------------------------

Normally, when a [code] or an [animation] is
listing for value changes of a [tag], it is not
guaranteed that all values that the [tag] assumes
are viewed by those listener. When a [tag] changes
its value (to 1, for example) an event is posted to
all listener, but the [tag] value could change its
value again (and becomes 2, for example) before the
1 value was seen by the listeners. A mailbox [tag]
is guaranteed that lets all the listener to view
(and process) all its values, even through
[clients/server] communication. The mailbox
dispatch mode is useful if you need to post some
values via a [tag] and you want the listener
[code(s)] to view and process all posted values,
even for very closely posts.
