@GDU ~ got the same issue here, and then I discovered that, as of bbPress 2.2, bbPress will auto-detect the CSS file if it exists in the right location.
Directions to use custom CSS file without a plugin
Copy:
wp-content/plugins/bbpress/templates/default/css/bbpress.css
to:
wp-content/themes/[YOUR-THEME]/css/bbpress.css
That’s all it takes.
Oh, and maybe a little editing of the bbpress.css file, of course.
Hope that helps.
Terence.
