English spelling

On Skype, one of my friends from N.Y. helped me to check my contents in English in my blog.

He easily found so many my wrong spellings in English. What a bummer! I want to tell all people whose language is English that non-natives have to overcome this problem too. I heard that there are a lot of spelling contests in schools in the U.S. I 'm just wondering how do they learn correct spellings by heart. Yes. we Japanese can remember how to write Kanji characters easily though it is really hard for non-Japanese people. But sometimes Japanese have hard time to remember it because they are too dependent on the computer word processing system in these days. I mean the computer word processing let us forget stroke orders and how to write some parts of Kanji characters.

Thanks to Google blog system, I can count on the spelling checker here. But too much reliance on it is not a essential solution. My contents in English on this blog might have grammatical strange expressions in English due to lack of my skill.

Can anyone tell me how to solve this serious problem ?

Thank in advance.
