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.

For a native English speaker (like me) it's very easy to see what people write - especially since I spend time around young children and have to try to interpret what they write. Bad spelling and grammar comes more of an issue with other languages, if you get your word order wrong in English, for a lot of sentences, it can be inferred what you are saying. For people in another native language, it's probably more difficult to try to translate as English is a fairly forgiving language in itself.

I would personally have no issue in people who don't speak native English therefore to post in both langauges while they are still trying to perfect their English skills and it can then be translated from the original verson or someone could offer constructive critiscism on some of their spellings (and I doubt a moderator would delete such a post if someone has at least attempted to write the English version above - I've written in two languages before and it's not been deleted by a moderator).
