Hi all,

I have an idea for a website. I will be giving away free gifts if visitors to my site can get 50 of the friends to also visit. I plan to have several gift opportunities (thus several pages so I can display more ads)

I have a couples of questions:

How would I go about creating a website which knows when 50 unique I.P's have been "linked" from somebody else?

Is it worth it?! The free gifts will be inexpensive but will still attract visitors.

I hope somebody can help!

Many thanks, Justin.

I guess you may integrate your site with google analystics and it will give you a complete statistics report of visitors on your site.
