Write in clear, grammatical, correctly-spelled language
Most of us have found by experience that people who are careless and sloppy writers are usually (there are exceptions) careless and sloppy at thinking and working on cars. Answering questions for careless and sloppy thinkers is not rewarding; we'd rather spend our time elsewhere.
So expressing your question clearly and well is important. If you can't be bothered to do that, we can't be bothered to pay attention. Spend the extra effort to polish your language. It doesn't have to be stiff or formal in fact, the car culture values informal, slangy and humorous language used with precision. But it has to be precise; there has to be some indication that you're thinking and paying attention.
Spell, punctuate, and capitalize correctly. Don't confuse "its" with "it's", "loose" with "lose", or "they're" with "there". Don't TYPE IN ALL CAPS; this is read as shouting and considered rude. (All lowercase is only slightly less annoying, as it's difficult to read.)
More generally, if you write like a semi-literate boob you will very likely be ignored. Writing like a l33t script kiddie hax0r or a gangsta from the ghetto is the absolute kiss of death with us and guarantees you will receive nothing but stony silence (or, at best, a heaping helping of scorn and sarcasm) in return.
If you are asking questions on our forum and English is not your native language, you will get a limited amount of slack for spelling and grammar errors - but no extra slack at all for laziness (and yes, we can usually spot that difference). Write in English. We will flush questions in languages that the bulk of our users don't understand, and English is the working language of the Internet. By writing in English you minimize your chances that your question will be discarded unread.
