I would be interested in helping out with building websites. I mostly do Python programming, but have dabbled in a lot of different languages. I built basic websites in school (as a design major), but as a self-taught programmer, I've always been concerned about making that leap to being responsible for security.
Let us knowledge share, I know many languages but can only hack at python.
Build what you want to build, what you think may be fun. I will help, and others too.
