Mambo Means Content Managment Open Source Style

According the MamboServer.Com website, Mambo is: " … one of the most powerful Open Source Content Management Systems on the planet. It is used all over the world for everything from simple websites to complex corporate applications. Mambo is easy to install, simple to manage, and reliable. "

I tried out the admin system on their demo site and was very impressed. The most interesting feature is the ability to add RSS streams right onto your website.
