HTTP Referers
This page will show to you who is linking our site.
The referers list will be very big if you can't maintain it. You
can also deactivate this feature editing config.php file
and changing the value of $httpref from 1 to 0.
Don't let this register to be very big because it can decrease
the server performance, so at least one day in the week delete
it by clicking on the Delete Referers button.
