Forgive me if this has already been suggested, I have had a quick look to see.
The idea
I would like to suggest that a user be able to decide how notifications from Moodle are sent to them. For example via twitter, Google+, Linkedin, email, Facebook or some other social solution that they are using. The message or notification of the message would be sent to their smartphone and then they get a Ping telling them that they have a message.
I believe that this would work best from their user account details where they can indicate their preference themselves and setup the connections. It would also be useful if it could be selected using the Uploading uploading users .csv.
The why
There is a problem that students generally do not use emails and so miss important messages and communications from their institutions and Moodle. Recently after performing a survey a number of students told me that they are sent email but no one tells them! Initially I thought well you can manage to breath without being told so surely you can manage check your emails.
I believe that this stems from a) students don't use email in their normal lives and b) many institution's email solutions are not easy for the student to sync their smart phones to.
I saw a demonstration of the Canvas VLE and they have this feature and I really like it.
Your comments please
Cheers
