If you are fluent in a language other than English and would like to help out, there are still lots of great opportunities. If you only have a small amount of time, why not copy edit a single article? (Copy editing basically means proofread it, correct any spelling or grammar mistakes, and rewrite anything that is not written clearly enough.) If you have more time, you can translate an article or two. Pick your favorite. If you’re really ambitious, you can sign up for the 4-part Painless Functional Specifications (still available in most languages) or the 9 chapter UI For Programmers, available in every language except French and Spanish.
