SAVmee is a question/answer Platform for groups of developers. You can create your own teams and answer each others questions. It was developed at Code+Design Camp Stuttgart 1808a by friends of mine and me.
At the Beginning of the Code+Design Camp in Stuttgart, we were told to talk to other people, if we had problems regarding our project. At this moment the idea came to our mind. We would build a platform for all members of the camp, to ask questions and the people with skills in that field could then answer them. So there was no 'ahhh, i can't help you with that, but maybe ask ...'
Stackoverflow actually built the exact same service (see Stackoverflow Teams) the only major difference is, that our service is free and without any warranty ;-)
