If you don't have root access on your server, you need to email your hosting company and ask them to set up the cron tasks for you. After you've configured your cron files for the correct path, etc., just write to your host and request something like this:
Run: /htdocs/mysite/mydomain.com/ubbthreads/cron/php/subscriptions.php nightly around 1:am
Run: /htdocs/mysite/mydomain.com/ubbthreads/cron/php/doexpire.php nightly 1:am
Substitute whichever time you want to run subscriptions and/or doexpire. I thought I should post this because I had no idea how to word my cron request, so Josh helped
