BuddyPress.org

Wordpress Version: 3.3.1
Current Theme is: BuddyPress Default 1.5.4

I’m having issues trying to locate which file I need to edit in order to make the sub topics be on separate lines.

Currently the topics are in a paragraph separated by commas like so:
MAIN CATEGORY
Topic One (0, 0), Topic Two (0, 0), Topic Three (0, 0), Topic Four (0, 0),
Topic Five (0, 0), And So On (0, 0)

I’d like to put a
where the commas are so that it would look like so:
MAIN CATEGORY
Topic One (0, 0)
Topic Two (0, 0)
Topic Three (0, 0)
Topic Four (0, 0)
Topic Five (0, 0)
And So On (0, 0)

I’ve tried:
forums-loop.php
page-front-forums.php
but I think I’m on the wrong track as neither of those make a difference.

Thanks in advance!
