Dear Programmers, A visitor referral/affiliate script is required to track a visitor's referrals. There are several free scripts already available which are used to (refer-a-friend), but we need a few modifications. We need the script to do the following: 1. When a visitor (User 1) comes to the site, there is a ?refer-a-friend? link which the visitor enters their details and those of which they wish to refer the site to 2. When a friend (User 2) of the visitor visits the site, we can see who referred them (User 1) There are many freely available scripts for the above, but we need a few changes as the above will only track the first level (Visitor - Friend referral). We need the script to track several levels deep. 3. When User 2 visits the site after being referred by User 1, they too will refer the site to other friends (User 3, User 4, and so on?.) 4. The script must track the other friends and who referred them in the beginning (eg) If User 1 refers User 2, who refers User 3, who then refers User 4, we must see that User 4, was referred from a chain originally started by User 1. Please ask any questions through the PMB and show a working demo if possible. Please do not bid if you are not sure, ASK FIRST! Thanks and happy bidding!
