Hmm. The English in this post is probably already above the average level of English as written in the US. I suppose one thing you could do is to simply encourage your correspondents to point out your errors. A little humbling, perhaps, but there's a lot to be said for rapid feedback. You didn't ask, but here's a little: English in the sense of the language is invariably capitalized. okay is perhaps a more correct spelling, though many use OK or ok informally. most of the information sounds a bit odd. Maybe just most things. Probably when I have made. You're missing a couple of periods at the end of sentences. This is all rather trivial, though. Your (written) English is essentially at a native level.
