Yes, I do agree with this. Learning and being more active in the local board for someone who is joining this forum for the first time and doesn't have enough knowledge and if they have problems understanding the language will really help beginners to adapt to this forum more quickly and so they understand more and get to know developments about crypto in accordance with a language that is easy for them to understand, namely their respective national languages.
But keep in mind that if beginners are only active and contributing continuously to the local board, I think they will never develop and will never gain more knowledge, they must also follow and add to their insights about crypto developments from various points of view including from general/global threads in order to have a broader and more complete understanding and knowledge. For the problem of a lack of understanding of English, which is an international language in my opinion it shouldn't be a thing that prevents them from being active and contributing to global threads because they can use an automatic translator at any time in the device browser they have.
