@MichaelEcklund Hi. Do you mean like source guardian?
There is an option to include your source too while setting the checkboxes about your package's content, so I assume you can. But I suggest you go with the MojoMarketplace. Envato's reviewers need some sense to be talked into them.
I have a question about publishing an item on WordPress theme directory. What if your theme does not render properly on wp-themes.com? I mean for example, a restaurant theme. You need to add content to it that is different from the wp-themes.com.
If you fill it with Test Unit Data, it would be just...rubbish.
