Comments.Text: I want to show all tags that are in use. 
  
  E.g. 
  If `2015` has an entry, show.
  If `2001` doesn't have an entry, don't show. 
  If `2017` has an entry, but `fellowStatus` light switch is off, don't show.

ThreadText: # My `for` loop has fallen...and it can't get up
  
  (Asked by: username_0 on 2018-04-27)
  
  I want my `<ul>` to show a *single* tag representing all "active" entries ( "active" using a custom lightswitch field in the entry: `fellowStatus`.
  
  Each tag is a year (e.g. 2014, 2010, etc)
  
  E.g. if there are no "active" entries with the tag `2017`, it should not display.
  
  The code block below spits out only tags where entries are "active"
  BUT...
  It spits out duplicates of each tag depending on how many entries are using it. (e.g. It displays 8 instances of `2015` instead of 1)
  
  ```
  <ul>
  {% for entry in craft.entries.section('fellows').limit(null) %}
  
    {% set tags = craft.tags.relatedTo(entry).limit(1).find() %}
    {% set active = entry.fellowStatus %}
  
      {% if entry.fellowStatus == 0 %}
  
        {% for tag in tags %}
            <li>
              <a href="{{ tag }}">{{ tag.title }}</a>
            </li>
        {% endfor %}
  
      {% endif %}
  
  {% endfor %}
  </ul>
  
  ```
  
  **Tags:** tags, forloop
