Hi Blanca! I’m not sure if this is a good idea. Please, consider that Discourse is a fast developing environment where people from all around the World participate.
My mother tongues are Spanish and Galician, but I find reasonable and far more productive to use English when communicating with the community about installation, management and development issues. Our, at least my, poor English has never been a barrier in meta.discourse.
A different thing is to work on a good quality translation of the Discourse at user and management of the site level. I have not looked at that point yet. As a newcomer, I first need to work out a lot of doubts about all the bricks building Discourse. I will be happy to contribute to it at some point hopefully in the near future!
Just my two cents! ¡Saludos!
