Hi DP Members, I need some real help... I am setting up a promotional system online for an offline business in my area. My problem is I need to make a file that we're letting people download for free only a ONE TIME download. Meaning, once they download it they cannot download the file again because the site won't let them. How do I do this? I want a setup like the one at http://rapidshare.com/ They won't let you download stuff for free after your download it once. Or at least, something like that. I hope my question makes sense to you. I need it to trace the person's IP address to prevent them from printing a coupon twice, right? Thanks for those who reply... And please tell me HOW and not just WHAT. I would greatly appreciate it. It would be even better if I can make a PRINT NOW feature and only allow the to click the PRINT NOW button ONCE. After they print it once the feature becomes disabled and they can no longer, in any way, print the coupon again. Again, please tell HOW. Thanks. -John
