I am trying to run a competition on my blog with a viral component.
The short version:
1. User 1 is sent an email to enter a competition
2. In order to enter, they go a page on my blog and fill in the names and email addresses of 5 friends.
3. Their friends receive an email saying that they have been referred by their friend User 1 to enter a competition.
4. They can choose to enter by filling in the same form.
Please note - this is not aimed at generating email addresses, but rather at generating awareness for my brand and for the competition. Does anyone know if such a plugin exists?
