Do you have specific tasks that you do on a regular basis and would like to automate their creation? MSCRM doesn't have the capability to do this out-of-the-box but with a few new fields and a simple workflow, you can do it yourself.
The only field that you need to create is an option set for the recurrence frequency. I called the field "Recurrence" and the options available are None, Weekly, Monthly, Quarterly. I'll review the workflow April's Tips & Tricks Google Hangout so make sure you join us!
