5. And don't start a sentence with a conjunction.

The biggest reason we have for using full English on the forums, is some users might not be fluent English speakers and may have to use a translation service to view the page. If the page is full of crap then they aren't going to know what the hell anyone is talking about. If full English is used, it'll be a lot clearer for them.
Google Translate: English-> Hello how are you Spanish-> ¿Cómo estás English -> Hello, how are you? Spanish -> Hola,¿cómo estás?
