Hello, I'm looking for document describing all email notifications?

There is a description of all the email templates at the bottom of this page: http://www.activemodules.com/active...el-design/

If you have any specific questions I would be happy to help.

You can assign some of the default settings on the Settings and Journal pages in the control panel. There is no option to change the default settings for Notifications though. There will always default as enabled.

Thanks for link, it'll help me to prepare nicer email notifications

Another questions:
How can I set up email notification if I update my Status in My Profile?
Can I enforce that new user or new Group member will have all Notifications ON in default?

1) You can not set up notifications for status posts on your journal, because other users can not "subscribe" to your journal.
2) The only option right now is opt-in subscriptions.
