Add a new language to Transifex


one of my colleagues asked some months ago to add the eu_ES language to but he hasn’t received any answer yet. I can see that there are two requests (eu and eu_ES) without any answer:

Please, who is in charge of accepting new translation languages in Transifex for Open edX? Could he/she accept the eu_ES language? and if not, how can we proceed in order to be accepted?
