Getting Involved in Programming Language Standards?

Carnage4Life asks: "After continually being surprised by the evolution of various programming languages (the most recent occurances being the change in meaning of the protected keyword in Java, as well as the addition of the restricted keyword in C) I've decided that I wish to get involved in the standards process for a variety of languages. This has proven to be easier said than done. So how does one get involved in the standards process for a particular language, be it C#, Javascript, Perl, C++, Java, C, Python, or any other language? I know each of these languages probably has a different process so please feel free simply to point out how to get involved in the languages you have knowledge about." Interesting question, but I think the best advice to fall back on is: "ask around". Most compilers and interpreters at least have the author's email address or a mailing list where these can be directed. With that said, has anyone done this for a specific language? If so, please tell us of your experiences.
