@Pavla-Bartošíková Ad "aiming to make it more universal and accessible for a broader audience" I was not convinced, but nevertheless the automatic translation on FB works correctly and smoothly. So I think we don't need another fanpage, because the one run in Czech users can with one click translate to the default language they have FB set in. My point is also that I find it tiresome to rummage through hundreds of fan pages that interest me, just because creators specialise/atomise their work in separate FPs.
But that's my perspective, I don't know much about social media and customer relations, so I believe the decision is an informed one.
Thanks for answer Pája.
