The incentive script consists of a global part, the subsites and adminpanel.
How it generally works: On a subsite the user can login with the global account information. Then the user sees a link on the subsite which he has to click - the user will be redirected to an external website where he will get a confirmation email. This confirmation email has to be entered by the user on the subsite - then he will get to the confirmation page.
Html and code need to be strictly separated by using templates.
A manual will be provided which has all basics and if I want to choose your bid I`ll send that to you and you have to confirm that you can do it.
The script is needed asap! You must be reliable, proactive and must properly test the whole script before delivery. Meeting the deadline (your set delivery time) is a must. Longterm relatioship for further development would be preferred.
