How do I change the avatar size in bbpress 2.0? It’s currently 80×80 and I want to change it to 60×60.

Already found it;

It’s in the plugins/bbpress/bbp-includes/bbp-reply-template.php

change the ‘size’ => 80, to 40

A better way would be to edit it in the template or use the bbp_get_reply_author_avatar filter in place.

What you did will work fine, however keep in mind that when the next version of bbP comes out you will lose the edits you made to the plugin.
