Refer system

Is there anyone installed Refer 2.1 ( in your DH hosting? I had installed this little script and go through the installation process well. But at the end, it seems didn’t work, I’m not sure DH support rewritable .htaccess. If you guys had installed this refer system in your site, Please share your experience to me.

By the way, If refer 2.1 can’t work with Dreamhost, is there any other script or third-party web app do the same thing like tracking visitor or link to the sites. Thanks
