English Translation
Before you organize the event, speak up.
It should be:
Antes de que organices el evento, habla.
or
Antes de que organice el evento, hable.
The way it currently is written is a mix of Ustedes and Tu.
Before you organize the event, speak up.
It should be:
Antes de que organices el evento, habla.
or
Antes de que organice el evento, hable.
The way it currently is written is a mix of Ustedes and Tu.
This sounds to me like it’s mistranslated and should be ‘Before he/she organizes the event, (you) speak’. Because if it was you on both sides, I’d rather say ‘Habla antes de organizar el evento’.
