The Tox core has been shared all over the internet by inspired enthusiasts, and has drawn the attention of many developers. However, the clients haven't received nearly the same amount of publicity, and their developers need help to bring easy, secure communication to the masses. And since the core is a simple protocol library with an API (and with bindings available for many other languages), you can start your own client too. If you fancy yourself more of a low-level programmer, help with the core is always appreciated: https://github.com/irungentoo/ProjectTox-Core Developers are always present over at #tox-dev on freenode. For the API: http://api.libtoxcore.so/
