I saw that cmus is not actively maintained anymore, which is a shame. I love cmus and I depend on it.
Seems some people are trying to get some work done. If you want/need help with the website, I am absolutely up to helping out. I am also supporting the LaTeX project, also here (work in progress). Let me know if you are up to it.
Btw, I've just sent a pull request with some minor improvements.
