Hi Louise,
TMM offers NATS as a product which allows owners of Adult sites to create their own Affiliate Site where they can configure their own referral programs to incentivize others to promote their sites and increase their business.
TMM does have a referral program if you would like to refer people to use NATS as well at tmmcash.com (I can't post URLs yet
)
let me know if i'm understanding you correctly ;)
