You might be worrying a bit too much about what others think. I am English and if someone is, say, Russian, and writes to me in English, I don't care if their grammar is a little poor. The great thing about English is you can understand even when most of the words are in the wrong order :-)
Also, most English people don't know much about grammar anyway and lots of people still confuse things like there/their/they're; are/our; its/it's etc.
