Graham tiaxgame This version of "related posts" has the related posts list under the "tags"
The outer div for the related posts now has the class "xt_blog_related_posts"
Showing "related posts" after a new comment has been fixed
The __blog_block_id variable is required for it to work
It is still based on the standard blog twig file so custom twigs may not work depending on what you change
