こんにちは、みなさん。
私は『青』です。
このスレは、英語で話します！
準備はいいですか？
では、スタートです！
Hello Blue! I'm Takao!
I can speak fluent English, as I live in England!
You have said "This thread is speak English!" but this is a mistake.
The correct sentence is "This thread is for speaking English!"
And also, you do not need to put the comma in the sentence "Hello,everybody."
The correct sentence is "Hello everybody."
I am sorry, I think I critisised you too much.
I will be hoping for a reply, see you then!
