As mentioned in this post, the idea of a recurring ticket is pretty valid. From time to time, we have to create repetitive tickets (like windows update tasks, restore simulation of backups, check firewall rules for unused entries, and so on).

I guess this is a very important tool for Service/Help Desk purposes, so we doesn't have to create a internal schedule (on Microsoft Outlook or Google calendar) to remember to open a new ticket every week/month/etc.
