Working with bbPress for the site's forum, I found GD bbPress Tools by Milan Petrovic to be a HUGE help in configuring, customizing, and extending bbPress functionality. It helps with everything you can think of, from BBCodes and signatures to script loading, custom-views, toolbar links, and way more.
Seriously it's a great plugin that saved me from having to install about five other plugins and other custom functions. It's like the missing Options for bbPress and definitely recommended for anyone running a bbPress-powered forums. Plus it's free and simple to use, so you can keep rockin' on down the highway.
Thanks to Milan and the team at dev4press for this gift to the bbPress community.
