Klein is bold and colorful WordPress community theme that has all the necessary features to build a highly successful community based website. It supports BuddyPress, bbPress and even WooCommerce. Forget that bland BuddyPress interface, Klein authors have put a unique touch to it.
A nice addition to the sleek and modern design is notification drop-down. It's probably the best way to notify users about the latest updates and events within the community.
The options panel is fairly easy to use so you won't get overwhelmed when customizing the theme. 8 base presets were included to match your brand without much trouble. Many layout options are available for different types of content.
