How to show posts related to a specific category?

Hello,

thank you very much for this awesome plugin! I would like to display the posts of a specific category. I′m using a Custom Post Type called “user” with taxonomy “user_category”. How can i display the items inside a category of this Custom Post Type? In this example i would like to show all items of the category “blog” which has the ID 39.

[mctagmap columns=”5″ hide=”yes” num_show=”10″ more=”more ?” toggle=”? less” show_empty=”yes” name_divider=”|” tag_count=”no” width=”100%” equal=”yes” manual=”” basic =”no” basic_heading=”no” from_category=”39″ show_posts=”yes” post_type=user” taxonomy=”user_category”]

Thank you very much!
