The newcomer homepage is a meant to be a place for newcomers to quickly get oriented and begin their work on their wiki.
I'm currently beta-testing the Homepage in Czech to double check it is working for Czech environment.
I have concerns about Growthexperiments-homepage-account-age message. At least for "1 minute", it translates to Czech as "Svůj účet již máte vytvořen 1 minuta". However, that's incorrect in this context. Correct localisation would be "Svůj účet již máte vytvořen 1 minutu". For 2+ mins, it works correctly.
I don't think how this work for other "1 x", but I think it works in similar way.
@MMiller_WMF, how much important this bug is?
