Yes we would. Just ask one and see.
I am Japanese studying English.
I am sorry for my bad English but would you answer my question?
Welcome, Yudai san. We will be happy to answer your questions. It doesn't matter if your English isn't very good. (It's better than my nihon-go.)
Yes, we would. Sometimes my English is bad. Thank goodness for spell check 🐮
Yes Dear Yudai,

Your English looks good to me. Ask away!
