Carlos, no need to take Nicolas reply as an offence - you're most welcome here. No one in this forum has English as mother tongue, so misunderstandings are easily made. Please keep that in mind.
Since we all speak a different language, in this forum the agreed language of conversation is English. It's clear that you were not aware of that and that is no problem - that is solved now.
As Nicolas said, if you want or need to discuss things in your own language, there are other places to do that. For translation issues that concern your language only, that is the preferred way to do so, because there you will find people that actually speak your language. Here you will only find a few of them. This forum is to discuss the Moodle translation tool - things that concern possibly all or at least a lot of languages.
Happy weekend to all.
Is there a forum in masters for Catalan and Spanish?
yes, but they are generic forums of moodle, not of masters (translations)
You can write about the Moodle translations into Spanish, both international Spanish and Mexican Spanish, in the forum for Traducción Moodle al español.
You can also send Moodle messages to the maintainers for the International Spanish language pack.
