Select the user. Click on Edit User (Tools>Authors2Categories) and select the categories he/she 
are allowed to post to. Click on Save when you are done.

<h4>Shortcode</h4>
All the options are available in the WP admin but you can also use a plain shortcode (as it was in version 1 of the plugin). The shortcode is [authors_list] and accepts the following attributes.
<ul>
<li>style (1,2,3)</li>
<li>columns (2,3,4)</li>
<li>columns_direction ( horizontal, vertical )</li>
<li>avatar_size (any number, example 500)</li>
<li>amount (any number, no limit by default)</li>
<li>show_title (yes,no)</li>
<li>show_count (yes,no)</li>
<li>show_bio (yes,no)</li>
<li>show_link (yes,no)</li>
<li>orderby ( post_count, post_date, ID, login, nicename, email, url, registered, display_name, first_name, last_name )</li>
<li>order ( ASC, DESC )</li>
<li>skip_empty ( yes, no )</li>
<li>minimum_posts_count ( any number )</li>
<li>bio_word_trim ( any number, leave empty for no trim )</li>
<li>only_authors ( yes, no )</li>
<li>exclude ( user IDs separated by comma, example 1,3,4 )</li>
<li>include ( user IDs separated by comma, example 1,3,4 )</li>
<li>roles ( roles separated by comma, example administrator,editor )</li>
<li>latest_post_after ( for example if set to 7 it will only show authors that have posts published in the past 7 days )</li>
<li>name_starts_with ( limit to authors whose display name starts with specific characters )</li>
<li>first_name_starts_with ( limit to authors whose first name starts with specific characters )</li>
<li>last_name_starts_with ( limit to authors whose last name starts with specific characters )</li>
<li>categories ( category IDs separated by comma, example 1,3,4 )</li>
<li>terms ( term IDs separate by comma, example 1,3,4 )</li>
<li>taxonomy ( name of a taxonomy, for example post_tag )</li>
<li>title_element (the element that wraps the name of the user/author, defaults to div, can be any element, for example h2)</li>
<li>link_count (yes, no)</li>
</ul>
Example usage with attributes:
<pre>[authors_list style="2" columns="2" amount="4" show_count="no"]</pre>
There are additional attributes for custom content before and after each element:
<ul>
<li>before_avatar</li>
<li>before_title</li>
<li>before_count</li>
<li>before_bio</li>
<li>before_link</li>
<li>after_avatar</li>
<li>after_title</li>
<li>after_count</li>
<li>after_bio</li>
<li>after_link</li>
</ul>
Example usage with attributes:
<pre>[authors_list before_title="My custom content"]</pre>
These before/after attributes also support dynamic user/author meta fields using
<pre>{al:INSERT_FIELD_NAME}</pre>
Example usage:
<pre>[authors_list before_title="My first name is {al:first_name}"]</pre>
They also support some dynamic output functionality. Currently supports displaying posts links and social links (Yoast SEO needed):
Example usage for posts links:
<pre>[authors_list after_title="{alf:posts}"]</pre>
<pre>[authors_list after_title="{alf:posts type=plain amount=5}"]</pre>
Example usage for social links:
<pre>[authors_list after_title="{alf:social}"]</pre>
Example usage for roles:
<pre>[authors_list after_title="{alf:role}"]</pre>
Example usage for link (the “to” parameter accepts foollowing values: archive bbpress_profile buddypress_profile):
<pre>[authors_list after_title="{alf:link to=bbpress_profile}"]</pre>
