We hate long terms and conditions. So this is it, kept short and definive:
If someone buys our product when visiting our site via your affiliate link, you'll get a commission. Commission amount is 20% of the net payment of the customer (unless agreed otherwise). Commissions are paid around once per month, paypal only, so make sure to enter your paypal e-mail in your "Edit Profile" page @ https://www.itmightgetloud.org/affiliate-home/?sub=profile after the registration.
We are not responsible of your taxes etc. so you'll deal with them yourself.
