On 1 September 2017, Emiliano Llano Díaz said he was going to update the Spanish translation, so he is the assigned translator. He is forum user elld.
For details, you can ask me or write here.
Hi Emiliano,
Can we coordinate?
I will have 35 available hours starting tomorrow to help with the Spanish translation as a result of SUSE's hackweek (https://hackweek.suse.com/16/projects/learn-qt-linguist-and-improve-translations-for-fet-a-timetable-creator)
Did you already started your working on this?
Oh, sorry, Julio, but Emiliano completed the whole translation. Maybe you can collaborate in the future, though.
