Sorry guys i have no idea what other forum to put this in. Im am an owner of IPB but my partner bought IPB for my website so i cannot post in the customer section.

I've almost got the feeling that this is a part of a standard IPB release but i have not found it.

How do i find out who is linking to my site, my portal probgram has a referrer logging system in place so i can find out, has IPB got it

Not that I know of.

What you and your partner may want to do is to create a joint account that gets the IPS Cust access and to use that for support questions.

As for the referrer, I think you'll have to rely on 2 things:
Your hosts referrer logs
Search engines that refer to your forums.
