Here you go.  You may like to ask someone from Great Britain, Canada, Australia, etc. if they recognize any of the ones I have flagged with a question mark.  Also, when you write a colon, it is done like this: The colon is placed just after the last word in the phrase, and a space is entered, and the next word begins.  The next word is capitalized for a complete sentence or typed in small letters if that word only begins a phrase.
