It is good that you are suggesting members to improve their writing skills and grammar. I see it in a different way. Most of us had different upbringings, we got different type of schooling , guidance and friends. Most of this was not under our control and our learning of everything (including English) was affected by this. I am fine with people being able to convey their message even if there are minor mistakes in the content. I consider myself as no expert either and it took me a lot of effort to reach current level. Everyone who has a positive attitude can improve their writing skills to some extent but drastic change is impossible.
