These programs allow your visitors to recommend your sites to people whom they know, by filling out a form. The revenue model involves including checkboxes for subscriptions to offers and newsletters, for which the publisher will earn a bounty, along with adverts shown to the visitor after submitting the form.

Focalex - Signups for email subscriptions, co-registrations, and Tell-A-Friend (TAF). Net 30, minimum $25. International publishers OK, with some exceptions.

Opt-Media - Net 45, by check or PayPal. International publishers OK.

TAF Master - Customizable forms, and the ability to insert your own banners into the sign-up page, and to build your own mailing list from submissions. One login for all of your sites. Pays 60% of revenue, at Net 30. Requires at least 1,000 visitors per day, with US-oriented traffic. Only publishers from the US, Canada, the UK, or Australia accepted (other publishers with US traffic can request an exemption.)
