Thank you for your answer. That will be much helpful if the vocabulary is more understandable for the user.
To be more precise I would like that when a user register, it is automatically subscribed to the Daily Digest and does not receive anything else. So from my understand of your settings, the default settings for that would be :
Receive Notifications No
Forum Digest Preferences Daily
Maintain Global Notifications No
First: is those settings correct ?
Second: is there a way to make them the default settings for every new user ?
