I have to say that I love your Q&As and am an active member in five of them. They are so good actually that I would like to ask if I can get involved.
Let me explain a bit. In our secondary school TŠC Kranj we would need a good Q&A for math, physics, and programming so that our students could contact professors easily in case they had any questions - we are striving to increase the knowledge standards. I would need a Q&A to include a LaTeX based editing "MathJax" (like on Physics Stack Exchange) and a "code" editing tool for programmers. And your sites have it all.
Is it possible to get my hands on the code for this site so I could edit it and reuse it for our school? I saw it is a CC licensed - this is why I am asking. What are my other options? I can ask the principal if he would invest some money in a Q&A like this.
