Sure, in this thread, pls use English to discuss, and remember you don't need to use the formal English, we come here for "cutting the wind", right? So, try to use the conversational English
About the mistakes, are you sure that you don't have mistake when using Vietnamese? Are you sure you can talking in Vietnamese without mistakes? And what about Vietnamese grammar? I'm sure many people here have a lot of mistakes with Vietnamese grammar rule when writing or speaking.
Please excuse the mistakes, anyone who are afraid of making mistakes pls make mistakes by talking here, don't be shy.
I think we have a topic to discuss here: Correct the mistakes for each other immediately or not?
In my opinion, pls don't try to correct them, it's not good for others, when someone speak or write something wrong, and you show the mistakes, that people will feel embarrassed, and after that, they will not say anything 'cause they're afraid of mistakes
PS. My English is not good, because English is not my first and also my second or third language
