On #1, we had someone login from Germany and they were pleased to see the interface in their language. However, it was noted that some of the translations on the interface were not quite correct. If we wanted to fix those translations, could we do that? Let me know if this helps.

Please see our documentation on this: http://www.jivesoftware.com/builds/docs/clearspace/latest/Internationalization.html (Translating the Clearspace Interface). I haven't personally done this you'll need to extract the i18n file from the jars (as described in the documentation) and find the entries you would like to modify.

On #2, thanks for your answer, but what exactly does this mean? "however this doesn't necessarily enforce English as the language displayed." If we set this up in the admin console, you are saying that it does not necessarily default to English everywhere?  Or it does, but people can change their settings at the user level? I'm not quite sure I understand. If we set it at the admin level and it defaults to English and people can change it at the user level, I think that's okay.

Essentially there is a hierarchy for the locale. You can set the global locale, but users can set their "personal" locale and it will override the language displayed for this specific user. Hope this makes sense,
