Supervisor for Simplified Chinese translations has not approved new translations for a year. So far, there are over 200 items pending approve.
And there are many errors and outdated content in the simplified Chinese translation.
Are there plans to add new Supervisors? Or, future Simplified Chinese translations will be approved by the LimeSurvey Team?

I don't think anyone responsible for this will read this in the forum.

I'd write directly to the support of the Limesurvey GmbH.

Unfortunately this happens. Sometimes the supervisor has moved on and doesn't use Limesurvey much and things get "stuck".

But sending an Email they might give those translations free quite quickly I think.
