I am a newbie and have only basic HTML programming skills. I started a site and I want to keep track of each visitor's purchases, so that I can donate a portion of their purchases to the charity of their choice. I understand that the SID function in CJ (its called signature in Linkshare) is how to do this. Is there a way to generate a SID for a user and then automatically place the SID in the link? The programmer, who I paid and was supposed to know how to do this, flaked on me and won't return calls. Maybe the real question is: does anyone know a good programmer?
