Which is the best free help desk/support ticketing system according to you?

Thanks!

PerlDesk (http://www.perldesk.com/) is free, you might want to try that... even though it's free, it's probably the most popular helpdesk software used around here.

one or zero (php) is good....
try sourceforge.net and hotscripts.com
you will find so many....

:D

Thanks but nvm decided on cerberus.
