As stated before, I don't mind if english is not the persons primary language. We all need to start somewhere.
I say this because I own an international gaming server & I also speak 3 languages (English, Japanese, & Cantonese). My english & Japanese are fluent but when I write in Chinese I can see some people getting frustrated.
If you at least take the effort to at least spell check with firefox like you are doing, this will at least reduce some of the poor grammer & allow those with less of a language background to understand.
