[arch-general] A question about running Proftpd

Hi all, Have just installed ProfTPD and if I run /etc/rc.d/proftpd start as root it stats just fine. In /etc/proftpd.conf it says to run the server as the group nobody and the user nobody. I am just wondering what system level it's running on? Is the server now running as root or what privilegies does it have to the system? I suppose it is not running as the root user then? Many thanks for any info, Christian
