you would I think do better amending the files that display the forum

the hierarchy for these is

SINGLE FORUM

bbpress 2.6.6\templates\default\bbpress\content-single-forum.php
lists sub forums (if needed) using loop-forums.php
calls
loop-topics.php
calls
form topic.php

bbpress 2.6.6\templates\default\bbpress\loop-topics.php
does topic list headers

calls loop-single-topic.php

bbpress 2.6.6\templates\default\bbpress\loop-single-topic.php
lists each topic in the forum, last post and freshness

lists topic content.php

My standard text for how to amend bbpress template files is below with loop-single-reply.php as an example

find
wp-content/plugins/bbpress/templates/default/bbpress/loop-single-reply.php

transfer this to your pc and edit

and save

create a directory on your theme called ‘bbpress’
ie wp-content/themes/%your-theme-name%/bbpress

where %your-theme-name% is the name of your theme

Then transfer the file you saved above and put in in the directory called bbpress that you created above, so you end up with
wp-content/themes/%your-theme-name%/bbpress/loop-single-reply.php

bbPress will now use this template instead of the original
