@ Ned Flanders Yes, all words should be capitalized, as per Mibba rules. I have a story titled, "Hello? Journal? It's Me, Frank." I completely understand the complet sentence as a title deal, but all words must be capitalized.
Oh, I have a question! So, my new story is called Am I just sending words into outer space? and I'm a little confused because, being a question, are all words supposed to be capitalized? Because it looks better, being an actual full sentence, to have the words written normally, at least in my opinion. But should I capitalize all the words and be Am I Just Sending Words Into Outer Space?
