that is right.

you should ftp the script to an unprivileged user account, as the user
id and the passwort are transmitted in plain text.

then, move it to to the cron directory by moving into the upload
directory and, su to root and type

mv scriptname /etc/cron.hourly/scriptname

give it the permissions you want, maybe change owner and group, if
necessary, and you`re done.

there is a simple entry in the crontab, that every hour executes all
files in the /etc/cron.daily dir, every six hours in the .quarter-daily
dir and so on.

go to /etc and type cat crontab so see the entries (they seem to be a
bit confusing). type man crontab, and soon you`ll understand :-)
