Edited out as when click through link just says referred by a friend doesnt say who in top left hand corner
It probably is still tracked, maybe you can confirm with Octopus?
I tested the link myself that I posted on here, possible nobody will use it anyway, my link displays what it should display until it was posted on here and clicked through to test
There is another posting for Octopus from another member here which seems to work fine. Anyway let us know how it goes
