Log in as admin, then edit the user account.
For instance, https://community.nodebb.org/me/edit then Change Email.
Yes, there is -- you can set the language from the user control panel or from the admin control panel.
@julian Yes, thank you.
@julian I set the default language to zh-CN in my site. However, it still shows the home page to English. I understand it set its language based on browser preference language. You can see my site at c.mainnote.com which "register" and "login" were showing "English". I wonder if there is a flag to configure the whole site into default language.
Hi @georgejxzhang -- in the same page, there should be a checkbox that says "自动检测游客的语言设置". You can check that off to assume zh-CN default.
Thanks. It works. I cann't believe I ignored this flag previously.
