Hi all. I have a social networks site build with drupal and I have a problem with notification and organic group.

I'm subscribed to a group so when an user write something or reply to a post I'm notificated about it via notification module, but my problem is the sender: the user and not the group.

For example: userX write a post in groupX. Notification module send me a private message where it say that userX has writed a private message to me, but this is not true. userX has writed a new post in groupX.

How can I change it ? Do I need to use another module ? Which one ?

M.
