Publishing tutorials What are my options for publishing tutorials?

I would like to publish tutorials for specific methods of statistical analysis using a third party software package with some of my own code for handling the data. Something along the lines of this example - Analysis of Diallels using SAS.
The tutorial you are referring to may be suitable for Protocol Exchange. These protocols are not peer-reviewed, and you can include supplementary materials such as computer code. Or else, if you think your method would have wide applicability, you could consider submitting to Nature Protocols, which is peer-reviewed.
