This week (and next Tuesday) will see three Test Days dedicated to internationalization and localization - support for languages and keyboard layouts other than US English. I've got a blog post
up with more details on the three events. Please, if you use or can help test any non-US English language, do come out and help make sure Fedora 15 provides a first-class experience to speakers of as many languages as possible. The testing is very easy and there'll be people on hand in IRC to help with any problems. Thanks!
