challenge?

[steijssen]

Hi,

I want to know how I should go about this one. I need to set up a site to which a user can subscribe, by entering a username and password. A user can ofcourse subscribe multiple times. This is something I don't want. I want each user to be limited to 1 single user account.
Since most ISP's use dynamic IP's for their customers, and cookies are easy to erase from the user's hard drive, I'm looking for an alternative that enables me to restrict the user to ONE single account, even if the user reinstalls his computer or something.
Just explain how I should go about this one, I'll figure out the code myself (if I can).

Thanks for reading this,
Thanks again for replying.

sorry ... but that's almost impossible.

Cookies are not a solution cause in cyber shops many people use same terminal.

like you said the IP address isn't a solution.

What you can do is ask for e-mail and compare it in the database. Of course everybody can have as much e-mail addresses as they want ... but it's the best solution.
