About 6 years ago I was sitting in a lecture at the university. It was obviously one of those quite dry and boring lectures, and apparently not only for me. I noticed one of my fellow students of the course was creating his own website. I looked from time to time at his laptop and the software he was using for his site seemed very interesting. So I asked him directly after the lecture what it was.
It's Mambo he answered.

Sigrid and I spent the following days with Mambo and we were so excited, we started quickly searching for an application to use this great new CMS. At first we rebuilt our company Web site with Mambo. It went very quickly, and we had nothing more to do.

Then we came up with the idea to build a web site for our city, and this led to a problem. We couldn't find a good component for a Business Directory. Well, we are both software developers so we developed our own component. Ok, not quite, we rewrote an existing one. This was possible thanks to the Open Source license which the original component was released. We had moved to Joomla by this time, and the idea of Open Source inspired us alot, so we decided to share our component with the Joomla! Community under the name SOBI.

We released the first version of the SOBI component at May 25, 2006. So we are celebrating the 5th birthday of Sobi today.
