+OpenChatter Pi (3.1415): Message Subtype
+========================================
+
+  To overcome the problems of crowdy walls in system notification, We have added features of **Message Subtype** in mail.
+
+mail.message.subtype
+++++++++++++++++++++
+``mail.message.subtype`` has following fields:
+
+ - ``Name``: fields.char(' Message Subtype ', size = 128,required = True,help = 'Subtype Of Message'),
+ - ``model_ids``: fields.many2many('ir.model','mail_message_subtyp_message_rel','message_subtype_id', 'model_id', 'Model',help = "link some subtypes to several models, for projet/task"),
+ - ``default``: fields.boolean('Default', help = "When subscribing to the document, users will receive by default messages related to this subtype unless they uncheck this subtype"),
+
+mail.followers
+++++++++++++++
+
+In ``mail.followers`` we have added additional many2many field subtype ids :
+
+ - ``subtype_ids``: fields.many2many('mail.message.subtype','mail_message_subtyp_rel','subscription_id', 'subtype_id', 'Subtype',help = "linking some subscription to several subtype for projet/task")
+
+mail.message
+++++++++++++
+
+In mail_message we have added additional field subtype_id which Indicates the Type of Message
+
+ - ``subtype_id``: fields.many2one('mail.message.subtype', 'Subtype')
+
+mail.thread
++++++++++++
+
+ - In **message_post** method add the *subtype_id* field as parameter and set as default subtype 'Other'.
+ 
+        def message_post(self, cr, uid, thread_id, body='', subject=False, msg_type='notification', parent_id=False, attachments=None, subtype='other', context=None, ``**kwargs``):
+
+ - In **message_subscribe** method add the *subtype_ids* field as parameter.In this method if subtype_ids is None, it fatch the default true subtypes in mail.message.subtypes otherwise pass selected subtypes.
+   For update subtypes call **message_subscribe_udpate_subtypes** method
+
+        def message_subscribe(self, cr, uid, ids, partner_ids,subtype_ids = None, context=None):
+
+ - Add **message_subscribe_udpate_subtypes** method to update the subtype_ids in followers.
+
+    def message_subscribe_udpate_subtypes(self, cr, uid, ids, user_id, subtype_ids,context=None):
+        followers_obj = self.pool.get('mail.followers')
+        followers_ids = followers_obj.search(cr, uid, [('res_model', '=', self._name), ('res_id', 'in', ids)])
+        return followers_obj.write(cr, uid, followers_ids, {'subtype_ids': [(6, 0 , subtype_ids)]}, context = context)
+
+For Each Addons:
+++++++++++++++++
+
+ - Add data of subtypes for each addons module.
+ - Add subtype field as parameter in **message_post** Method for each addons module.
+
+How It Works:
++++++++++++++
+
+ - In addons module when we Follow a Perticular document It display under the followers button.
+ - In sybtypes there are 3 default subtypes for each addons
+    1) Email
+    2) Comment
+    3) Other
+ - In document display a default subtypes(which are true) related a perticular model_ids wise.
+    
+    Example:-
+        If I have open crm.lead, It display only subtypes of crm.lead
+
+ - When we select subtype it update subtype_ids(which are checked) in mail.follower where match res_model & res_id of the current documents.
+ - when message created update subtype_id of that message in mail.message.
+ - In Feeds display only those notifications of documents which subtypes are selected
