isplay all authors in an extended tab

Hi,

So I created a custom post type named ‘gd_article’ using the gd custom post type plugin. This custom post type is linked in ‘gd_place’ post type.

I created a new tab named Contributors in gd_place detail page and I want to display in this tab all the authors who linked there articles in a specific gd_place listing.

Any hooks or ideas how can I do this?

Best,
Derek
