Using Q&A Taxonomies with Taxonomy List Shortcode plugin

Hi Folks,

Q&A doesn't include shortcodes as such, however since it uses custom post types and taxonomies, you can easily use it with any other custom post type plugin, such as the following for displaying taxonomy terms (question categories are taxonomies).

I installed the plugin, but can not get it to recognize any of my question categories.

From the info on the author page:

http://wordpress.mfields.org/plugins/taxonomy-list-shortcode/

it should work in the format of:

[taxonomy-list tax=”category_taxonomy”]

But I can not figure out what to put in there.

I want to create pages that list all the questions and answers in each of my specific categories.

How do I do that?

Thanks!
