bbPress.org

yes, you have a choice

1. You could put it in your style.css – that is a file called style.css that you will find in your theme

wp-content/themes/%yourthemename%/stle.css

where %yourthemename% is the name of your theme

Just drop it at the end.

This will then override the code in bbpress.css, and is the easiest way

2. Otherwise you can create a directory called css in your theme

/wp-content/themes/%yourthemename%/css

and copy the existing bbpress.css across to get

/wp-content/themes/%yourthemename%/css/bbpress.css

but here’s the thing, you then need to find and edit the existing display lines, just adding code will give two sets, and your maybe won’t take preference

the lines you are looking start at line 904 and say

/* =Revisions
-------------------------------------------------------------- */

#bbpress-forums .bbp-topic-content ul.bbp-topic-revision-log,
#bbpress-forums .bbp-reply-content ul.bbp-topic-revision-log,
#bbpress-forums .bbp-reply-content ul.bbp-reply-revision-log {
	border-top: 1px dotted #ddd;
	width: 100%;
	margin: 0;
	padding: 8px 0 0 0;
	font-size: 11px;
	color: #aaa;
}

#bbpress-forums .bbp-topic-content ul.bbp-topic-revision-log li,
#bbpress-forums .bbp-reply-content ul.bbp-topic-revision-log li,
#bbpress-forums .bbp-reply-content ul.bbp-reply-revision-log li {
	list-style-type: none;
}

you just need to edit that to

`/* =Revisions
————————————————————– */

#bbpress-forums .bbp-topic-content ul.bbp-topic-revision-log,
#bbpress-forums .bbp-reply-content ul.bbp-topic-revision-log,
#bbpress-forums .bbp-reply-content ul.bbp-reply-revision-log {
Display : none ;
}
