Yes and thank you for your intentions on making the forum better! +karma ![Wink ;)](https://www.altcoinstalks.com/Smileys/default/wink.gif)
You're welcome, buddy!
How bad is the thread you are talking about? If it is hard to read and there can be some misunderstanding, we can try to deal with it. Try to make your own translation, let's see what other native speakers will say. If it will be better, it is possible that it can replace an old translation. As for me, I can read Bengali only with an online translator, so I can't evaluate it by myself anyhow.
No, It's really hard to read. As a native speaker, I can read it and understand what he was trying to say. But, sometimes, better wording can improve such guides. Since the forum does not have strict rules about it, I should not blame him for the work that he did free of cost.
Now, If you talk about my own translation, I can do it, but my translations take ages to complete because I have a lot of work, and I do translations in my free time. Recently, I also joined AOBT on BitcoinTalk as a main translator and I have done some work before. I guess I will apply for a translator badge at some point.
