The group email subscriptions default that commons in a box forced to ALL – it does not allows any change after that.
I click on Admin – than settings – then in email subscriptions defaults,
Email Subscription Defaults
When new users join this group, their default email notification settings will be:
NO EMAIL (USERS WILL READ THIS GROUP ON THE WEB – GOOD FOR ANY GROUP – THE DEFAULT)
than no matter the choice I made after I save it come back to ALL EMAILS
I open a ticket in
BuddyPress Group Email Subscription
The plugin author answered is Commons in a box forcing the default to all.
Thanks for help,
