However im not exactly sure where to find my unique id number could anybody enlighten me as to where it is?
Click on your name and then the "View Public Profile" option, and then look up at the address bar. It will say http://...member.php?u=xxx
, where xxx is your ID. So mine is 7 and yours is 1944.
Alternatively, click on the FAQs
link and, about three lines down, it will give you your full referral link with your ID in place.
