bbPress includes a rather dashing green dashboard style. Unfortunately it needs to be manually enabled for each user before it?s visible. 
This plugin makes the bbPress dashboard style the default across your entire WordPress install.
If you enable this plugin while bbPress is disabled (or not installed) it will display a warning message.
