There are only 2 steps:
1. Go here to donate at least $5: Childhelp
Make sure to enter your email address and you'll receive a thank you email from Childhelp. (It doesn't have any credit card info - I checked - so you won't be giving FTM access to extra Christmas spending money)
2. Forward the thank you email firstname.lastname@example.org and I'll reply with a link to download the FTM Holiday Mixtape. It's that easy!
