Spanish addresses

There is a patch in the extension module issue queue, but the author hasn't made the requested changes yet. The idea with the extension project is for users like you to create the modules that you need, then submit them back to the project. The Canada module that comes with cck_address is a model for you to use in creating an extension. It is actually quite simple; much more simple than creating a whole module from scratch for Drupal. Since the author for the Spanish module hasn't fixed his submission, I'll probably get around to it later this week myself if you can wait that long.

And since we're on the subject of contributing back, any module, like this one, could also use translation files (po files). I believe one other module of mine had a French po file submitted to it and I've included it from then on. Po files are created with many kinds of po editors or regular text editors that support the po file extension. See the Drupal Handbooks for more info on po files and translation.

I'm sorry I can't answer your question. Since I'm a native English speaker and everything is done in my language (and I don't have a need to translate anything to Japanese, my other language) I haven't had to do translation work myself. So I'll have to just tell you to look through the Drupal Handbooks for answers.

Please move this discussion over to the extension module project.
