Send Resource to a friend / Friend Invitation Viral Marketing:
For example if you have a "Resource" in the RM-Manager, then you could "send" this "Resource-File" (e.g. a .pdf-File) to a friend.
Well, you do actually NOT send the File itself via E-mail, but you just send a specific "Link-URL" to your friend.
The friend then needs to register at the website, in order to "view" or "Download" the Resource-File at the website via this specific Link-URL.
It is exciting because every user will WANT to register in order to see the File which his friend has sent to him.
human psychology works like this:
if a friend sends you an image or a file, then you want to see this image or file.... and therefore you will register at the website.... and probably also start to use this website.
Think about Megaupload.com , they had the same viral-marketing strategy:
You could NOT send a big file via E-mail to your friend. So what to do ?
You uploaded this big file to Megaupload.
Then you (or the system) just send a specific Link-URL to your friend.
Then your friend could go to Megaupload and download this big file via access to a specific Link-URL.
It is a very old, but free and viral internet-marketing-concept.
