Virtual Learning Network

Kia Ora,

I have two closed groups which I've set up on the VLN. Each time I change a file, or upload etc it sends a notification to people.  Does anyone know how to switch off some notifications and not others?  Ie I would really like the notifications from the discussions to still go out, but I don't want uploading of files to go out as a notification.  Any help would be most appreciated:)
