Perhaps I'm alone on this, but I tend to think in lists and post the same way - but without bullet points it becomes a nightmare for someone else to read.  Using returns (line spacing) to separate points turns it into a choppy mess.

Could you add a bullet point option into the message writing screen?  Or perhaps it's available if you know the code then, in that case, please share the code.

As an example of where this would help is one of my own gibberish-format posts.  You've been warned, so don't go cross-eyed trying to read it:
