This plugin allows you to take control over the execution of cron jobs. It's mainly useful for sites that either don't get enough comments to ensure a frequent execution of wp-cron or for sites where the execution of cron via regular methods can cause race conditions resulting in multiple execution of wp-cron at the same time. It can also help when you run into posts that missed their schedule.

This plugin implements a secret parameter and ensures that cron jobs are only executed when this parameter is existing.
