Configuring the activity Mails global

Hi Everyone,

i am using NC as a community solution and it grows more fast than i expected.

The Activity Function is getting horrible out of control, because in the beginning the users receive a mail about new, modified and deleted things, so that everybody is informed.

Now, while the NC is growing more users dont want this Mails and i need a way to configure the Users as Bulk oder As a Admin Config.

Is there a way to configure the Activity Settings for each User or for a group of Users as Admin?

Regards, Stefan
