+summary: 'Support for sending MUC messages to offline users'
+...
+
+Introduction
+============
+
+This module implements support for sending messages in a MUC to affiliated users
+who are not in the room. This is a custom extension by Tigase to allow push notifications
+from MUCs to users who are not currently connected.
+
+It is planned that this will evolve to a XEP in the near future.
+
+The protocol is described below. It is implemented in the Siskin client for iOS.
+
+Details
+=======
+
+Add to modules_enabled under your MUC component (i.e. **not** the global modules_enabled
+list). There are no configuration options.
+
+Compatibility
+=============
+
+Requires Prosody trunk (0.12) for the API introduced in commit 336cba957c88.
+
+Protocol
+========
+
+To enable this feature, a client must fetch the registration form from a MUC,
+as per XEP-0045. The form will include the usual field for nickname (this is
+required), and also a boolean field named `{http://tigase.org/protocol/muc}offline`.
+
+Submit the form with that field set to true, and the MUC will forward messages
+to your bare JID when you are not connected to the room. Two things to note:
+
+1. This will achieve nothing unless your server is capable of handling these
+    messages correctly.
+2. Messages are only sent when you are not in the room. This includes other
+    resources of the same account.
