Thanks, actually for that whole series on sidekiq. Maybe some testing coming up ?

Having deployed the cron, i had to restart the sidekiq service. Off course. 

As you have everything else nicely setup for copy/paste, adding the schedule.yml file would make it even easier for the next guy.

And i must admit that at first hearing i also understood that this was only for use with enterprise edition. Only a bit of checking and listening again cleared that up.
