How do I set my personal interface language to Traditional Chinese?

You can change this in two places with the same result: 1. Go to Personal Settings on the left, select Traditional Chinese in Interface Language under "Interface and Format," and save. The change applies immediately. 2. Or click the globe icon in the top-right system bar and select Traditional Chinese directly. Language is saved to your account and remains the same when you log in on other computers. Accounts without a previous setting default to Traditional Chinese and do not follow browser language. Interface language affects only your personal view, not documents sent to customers. When printing documents, you separately select Document Language. You can also set Time Zone and Number Separator in the same area—time zone affects the date and time displayed on documents.
