Affiliates whose referrals have successfully converted to actual sales are listed in your Transaction Log by their Email and account ID.
Typically, affiliates who never convert a sale are either just too disinterested or unmotivated to bother actually promoting your program (they may be "idle joiners" with dollar signs in their eyes who didn't really expect to have to DO anything), or too technology-challenged to be much success at online marketing anyway. It may be a better ROI to focus on your successful affiliates and ask them what you can do to help them be even more successful; maybe they have ideas to improve the product presentation on your site to make it more enticing, or maybe they'd like an "official" banner image they can use in place of their link text, that sort of thing.
You might consider joining your own affiliate program by clicking your own sign-up link, so you can see exactly what your affiliates would see when they join your program. Your existing E-junkie login will work fine for this, rather than having to register a new account to join; you can use the Sellers and Affiliates tabs at the top of our site to pick which Admin you want to see at any given moment. As you will see, the Affiliate Admin is fairly simple and straightforward, so you'd do better to teach your affiliates how to fish (get their own code) rather than just giving them fish (sending them link code yourself).
