Getting bbPress up and running is a snap. Simply install it, activate it, create some forums, and you’re off.
From there (just like WordPress) you’re free to keep it running it the way it is, add BuddyPress for extended profiles, group forums, notifications, and activity logging, or customize it to your heart’s content with any number of dedicated bbPress plugins or themes.
bbPress works nicely with single sites, multiple sites, and multiple networks of sites. A commitment to backwards compatibility means bbPress will stay functional and safe between updates, upgrades, and new versions.
