 Some activities that StatusNet needs to do, like broadcast OStatus, SMS,

+XMPP messages and TwitterBridge operations, can be 'queued' and done by
+off-line bots instead.
+
+Two mechanisms are available to achieve offline operations:
+
+* New embedded OpportunisticQM plugin, which is enabled by default
+* Legacy queuedaemon script, which can be enabled via config file.
+
+### OpportunisticQM plugin
+
+This plugin is enabled by default. It tries its best to do background
+job during regular HTTP requests, like API or HTML pages calls.
+
+Since queueing system is enabled by default, notices to be broadcasted
+will be stored, by default, into DB (table queue_items).
+
+Each time it casn, OpportunisticQM will try to handle some of them.
+
+This is a good solution wether you:
+
+* have no access to command line (shared hosting)
+* do not want to deal with long-running PHP process
+* run a low trffic GnuSocial instance
+
+In other case, you really should consider using queuedaemon.
+
+### queuedaemon
+
+If you want to use legacy queuedaemon, you must be able to run
+long-running offline processes, either on your main Web server or on
+another server you control. (Your other server will still need all the
+above prerequisites, with the exception of Apache.) Installing on a
