Getting people started is often the hardest thing. However, those who've already made investments in a platform or service can act as a means to help new subscribers get started. For example, someone on a weekly coffee subscription could share a code with a friend to simply try the service for free for a week.

This could be taken further by allowing the existing subscriber to add a personalised note or make a product choice they think would be best for the new subscriber.

How can you use the wisdom of more experienced users to get the uninformed started?
