cron question

I hope I'm writing to the right list. This isn't a question unique to SuSE. I've been to LDP, the SuSE admin manual, and a few other help pages. How do I give users access to cron? From what I can gather, the crontab for user egbert, for example, should be /var/spool/cron/egbert/crontab. Also, his user name shouldn't be in /var/spool/cron/deny. What am I missing?
