Messaging system

Think you could innovate the messaging feature over on musescore.com? Not only sending text but media and file uploads are made possible.

One may find it helpful if they can send, for instance, an arrangement of the recipient's work. Especially if they try to contact/reach those who seldom come or use musescore (.e.g. occasionally upload score every blue moon) or do not have (known) email. Plus there is no telling when they going to respond to a message requesting such form of contact.

It would be nice if I could upload the file (e.i. pdf, .xml, or mczs) via messaging and it would be there whenever the user comes.

Thanks.
