Actually, this newsgroup is defunct. Active Perl newsgroups include
comp.lang.perl.misc, comp.lang.perl.moderated, comp.lang.perl.modules,
comp.lang.perl.tk, and comp.lang.perl.announce, with topics as
indicated.

I am guessing that you didn't write this script. You should know that
there is a Perl module to assist with CGI tasks (CGI.pm), including
parsing input data and generating HTML. Try executing 'perldoc CGI' at
a command line prompt to get more info.
Your script doesn't do any file locking. It will run into trouble if
two people try to post a message at the same time. If your script
encounters an error, it will die without writing the proper HTML, and
you will see nothing in your browser.
You might look into a different script for guestbooks. There is one
available at http://nms-cgi.sourceforge.net/scripts.shtml that includes
locking the data file to prevent simultaneous access by two users.
