Basecamp became the world’s most popular web-based project management app because happy customers have recommended it to their friends and colleagues. It’s been amazing to see how Basecamp’s popularity has risen primarily through word-of-mouth.

Basecamp Tell a Friend Contest
We want to help you spread the word to your friends, so we made the Basecamp Tell a Friend Contest. Here’s how it works:
- Sign up with your Basecamp account at https://tellafriend.37signals.com.
- We’ll give you a special link that you can tweet, share on Facebook, or email to your friends.
- Every person that signs up from your link for a paid Basecamp plan will get $10 off their first month.
- Every person you sign up counts as a chance to win one of our prizes.
This contest ends on January 2, 2012. Sign up today and start saving your friends $10 off their first month.

Good stuff. What would be nice is if the landing page mentioned the $10 off promotion.

I love seeing how much TLC you put into everything you do. It’s a great looking promo; an example of how to do it right.

Why can’t this work in reverse? For every customer I help sign-up, I get $10 credited towards my account?

@AC: Probably because you are entered into the contest?

Since each prize is over $600, minimum value you have to declare to the IRS , each is taxable income.
You might want to mentioned that on the prize page
