WebAIM recently announced that their free web accessibility evaluation tool WAVE is now available in Spanish. It’s a great tool for testing web sites, and there’s even a Firefox toolbar plugin!
WebAIM plans to translate the utility to more languages possibly Portuguese, German, Japanese, Thai, Turkish, and Russian. They are seeking volunteers to help; if you are interested, please contact WebAIM.
By the way, you can read a recent interview with Jared Smith of WebAIM from totallyaccessible.com.
