Yes! Once logged in, select Settings from the menu on the top left. Then, select Affiliate. We currently make payouts using PayPal. Once you enter and save your PayPal email address on that screen, you will be given a special affiliate link you can start using immediately. It will track all sign-ups and credit you.
The payout is 10% of the plan, recurring monthly for the life of the customer. We will eventually have an affiliate reports section built into our interface, but for now it's all manually done. The affiliate cookie is set for 30 days for any visitors using your special URL.
