in default setting for new users?
I found the email notification is too disturbing. However, the new users may not be aware of that and they may not know where to switch it when they right start to use forum. It's better to have it off in default seeting instead of switch it manually.
I did search and i found this is also required by other people but only for specific notification. I followed the guid to switch the follow after reply notification for email in the "Default users prefrence" extension.
But I still not sure how could I swith off other notification for email for the new users.
Is there anyone have done it before or have any idea how i can do this?
