i have a dreamhost account and am currently only hosting one client (i don't have a domain of my own)... in order to use the counter it asks me to enter the username of the domain that wants the counter. the only user name i'm aware of for that domain is the ftp username - could they be referring to another username?
Yes, it would be the same as the FTP user for that domain. You may have noticed that CGI is set to run as a certin user - that's the same as the user that has FTP access. which should be the same for a counter.
