Thanks for your comments. Yes - I agree there are issues when you install with whoever's ISP. But this script is already on over 1000 clients' own webservers, whoever they might be and hasn't run into any real problems. Well, none that couldn't be solved easily enough. We don't want to be doing stuff that would be site-specific, but I was expecting the CGI::Session module to be more commonly installed. Was it more recently released? The O'Reilly Perl book I have doesn't cover it, though it covers the rest of the CGI module. (book was rev. 2000)
