http://testbp.org/forums is the better place to look instead of http://testbp.org/bbpress/

Just enable forums component in BuddyPress. Bugle Notes is using the default theme for BP (with some CSS tweaks). If you download BuddyPress 1.1.3 and use the default theme provided with the download, your forum will look the same.

Testbp.org is using a new theme created for BP 1.2 (not yet released yet).
