Since 1.5 has been out for a few months now it occured to me to check how the translation efforts have been going. We had a ton of requests from our localization community that we addressed in the bugfix releases for 1.5 and we use the gettext translation framework, which (I’m told) makes localization a pleasure. Of course the place to go is the Codex, which has a page detailing over 35 language packs as well as about a dozen foreign-language sites from Hebrew to Turkish to Japanese dedicated entirely to that country’s WordPress community. Also my copy of the German WordPress book came in the mail today and judging from the screenshots it looks pretty comprehensive.
