Enable mail notification upon user registration

A Flarum extension that will enable mail notification by default upon each user registration.

Original Flarum post:

All credits goes to the origin maker, but it wasn't available on Packagist.

User preference will look like this for new users:
Preferences

Installation

composer require sinamics/flarum-default-preferences

Sinamics YESSSSS I NEEDED THIS!!!!! Thank you!!!!

emmm, i can't find where to set other users' setting of this function. Can you tell me where to find this setting, please?

chenjh12 There is no feature to adjust other user's settings in Flarum right now. Nor is there an extension as far as I know.
