Assigning moderators and displaying them in forums list; polls

Hello, I would like to learn how to nominate the person a moderator? I tried to make it by analogy to the previous versions - but it has not turned out.
P.S> also what happens with polls plugin?

More precisely why moderators are not displayed in the list forums?

Moderators definition

You can download 3rd party polls addon in Downloads section. In the nearest future, I have plans to work on my own version of polls, which can be inserted directly in messages, but not destructing the core of miniBB. It will a very rich addon, with many functions, and it will be released only as paid version.

To make moderators list visible on the first page (under forum menus), edit templates/main_forums_cell.html file and paste the variable {$moderatorsList} right after {$forum_desc} so for example it looks like this:

<tr class="{$bg}">
<td class="caption1" style="width:5%;text-align:center">
<img src="{$main_url}/img/forum_icons/{$forum_icon}" style="width:16px;height:16px" alt="" /></td>
<td class="caption1" style="width:75%">
<b><a href="{$linkToForums}">{$forum_title}</a></b><br />{$forum_desc}{$moderatorsList}
</td>
<td class="caption1" style="width:10%; text-align:center">{$numTopics}</td>
<td class="caption1" style="width:10%; text-align:center">{$numPosts}</td>
</tr>
