Designer Orientation 1.0 should help get you started as a contributor here.
Before you decide to become a Contributor please read the following:
Our Creative Commons
Designer's Guide to the Galaxy
First, if you haven't already, you will need to register here.
Next you will go here and let me know what your username is there so I can change your settings to "Contributor".
Now that you are a "Contributor" you will be able to follow this tutorial.
If you want to be added to the forum where that tutorial is posted please message me here.
I hope that clears things up.
If not please let me know what I forgot to mention.
Here is a fun instant preview editor for those who like to work directly with the code.
Then I just need your username for this site: http://blog.skemaholicsanonymous.com
