It is not a serious fault for user who/whom/whose/which/that don't use English as a first language. For a long time, since the day I left school, I have not yet check basic English grammar. Thank you for the warning.

Minor faults do not change average post quality or seriously change a good post to a shit one. You can write a perfect sentence, in vocabulary and grammar, but it neither does make your post looks helpful nor creative.
