Token to show all the comments including comment body for a node I am trying to set up a notification email using rules that will email a forum topic with all the comments including the comment titles and body. 

The Message text I have so far is: 


  A new forum comment has been posted by
  [comment:author:profile-main:field-name] with the following details
  
  [comment:node:title]
  
  [comment:node:body]
  
  Comments:
  
  [comment:node:comments]


However, the final token, [comment:node:comments], only shows the comment titles and not the comment body. 

Is there a way that I can show the full list of comments including the comment body?
To solve your issue you can create custom token which contain needed info. Basically you create a module that implements hook_tokens and hook_token_info. For more details see the documentation: http://api.drupal.org/api/drupal/includes--token.inc/7.
