Here are a couple of hints. We'll add more as we go. Feel free to add your suggestions.
Choose an effective title.
Be specific with your title. I have a question doesn't tell us anything. I need help with my relationship with my wife, lets us know what you are asking about.
Make it visually appealing.
I know a lot of you are used to texting, and so you type with no capital letters and very little punctuation. Combine that with a long post and you will create a post that is TL:DR (too long: didn't read.) At the very least, break up your post into paragraphs of no more than 2-3 sentences. That way the reader sees chunks of information. It makes it so the reader doesn't have to put so much effort into reading the computer screen.
More will be added as they come up.
