I would like to pass value to my join page for example my id (www.mysite.com/join?refuserid=124.
I have added the correspondent field (USER REF ID) to my user profile question.
So on my join page, the USER REF ID field should be inserted automatically by using $_GET[]. My question where I have to add the code in order to insert the value automatically without asking the user to insert the value of his/her USER REF ID?
Thanks in adavance, Lucas
