+
+Spectrum 2 can work as a [bouncer](http://en.wikipedia.org/wiki/BNC_%28software%29). When this feature is enabled and
+XMPP user disconnects, it stays connected to legacy network. All messages (even those from multi user chat rooms) are cached
+and once the XMPP user connects again, they are forwarded to him.
+
+### Enabling bouncer as a user
+
+Your client has to support Ad-Hoc commands. Then you just have to execute "Transport settings" command provided by the
+Spectrum 2 transport. You will see checkbox with "Stay connected to legacy network when offline on XMPP" label. When you check
+it and finish this command, bouncer mode will be enabled.
+
+If you now join some room, there is no other way to left it than disabling bouncer mode, leave the room and enabling it again.
