Importance of written English language on TA

[black hole]

You may notice that many people who do not belong to the Anglo culture or who are not from English-speaking countries make many or few mistakes in their written sentence. Do you even bother about grammar and spelling when you write something and post on the forums?
I remember the day, when I faced someone from USA who told me that my English sucked and that I had to improved it with such a hidden arrogance toward my personality, I forget his nickname. Now I realize than many people do not give a crap about it and they still continue their conversation with their broken English.

Communicating correctly adds a whole lot more weight to whatever it is you're arguing.

Well, as long as it's understandable, i see no problem.

Besides, English is not the native language of most users here so most don't care about such mistakes.

As long as you're not a native English speaker and you're not be able to speak it fluently without an accent, it should be the least of your worries.

Basically this. I mean, the English language is the lingua-franca language of the world where we can communicate with one another.
