So i added
to my config.php and it seems to kinda have worked (under settings -> email) users can now check "Send me a periodic summary of updates from my network".
But at what times are the mails actually sent out?
Or do if have to trigger that manually (or through a cronjob) every time by invoking sendemailsummary.php?
If so, why is there no documentation in the plugin on that kinda crucial part?
