CRON



Each hosting company is different so I cannot tell you

how to create a cron but it must be done to keep your

database in check.  



The file cron.php in your chirp installation directory

controls the deletion of old messages and waiting users

so that your database wont grow overwhelmingly large.



Check with your hosting company on how to create a cron

job using the cron.php file.



Typically you this would be the command and works for a 

large majority of the hosting companies out there.



lynx -dump http://www.yourdomain.com/cron.php



Here are a few options used by some hosting companies like

mediatemple.net



php5 /home/yourdomain/data/cron.php



or



curl --silent http://www.yourdomain.com/cron.php



I would run the cron once a day just to keep the cpu of the

server taxed only once a day.
