Alright, So, I've been wanting to develop a leads tracking script. I've started with the basics, using cookies to find out the visitors' IP address and location. Here are the two things I'm curious about adding: 1) Identifying Facebook accounts of website visitors who are logged into Facebook when they visit the site. I'm assuming I could use Facebook's API to get started... 2) Identifying the visitors' names and email addresses using cookies. I know this would be difficult-impossible for residential IPs, but corporate IPs should be easy, right? I'm not asking for someone else to do the work lol, I just want some feedback and/or suggestions from more seasoned programmers. Thanks, guys!
