Why did some of the original Mambo team decide to go elsewhere and create a fork?
Simple question without a simple (non-controversial) answer. As far as we are concerned, it’s ancient history and not relevant to where Mambo is today. The most important point is that the original Mambo is still very much alive and well. Under the Mambo open-source licensing agreement (GPL), anyone has the right to use the Mambo code to create a fork, that is, to create a special version of the software and distribute it freely. That’s the beauty of open source. There’s already a third fork running around at present and will probably be more in the future. Joomla may have been the first, but it won’t be the last time somebody bases a product on our award-winning code. In a way, it’s a compliment that people want to build on the code and customize it to meet the needs they see in the market. Open Source = Forks Happen.
