Scroll down to any of my posts with code. They don't have that nice numbering and highling everyone else's has. I wrote my code in a text editor, copied it to the post, highlighted it, then clicked "Code". I feel pretty confident I didn't click "Inline Code". Anyway, it shows up without the numbers and formatting. I didn't bother with the Markdown because I thought that was what the GUI was for. Am I doing something wrong?
Just looked at my posts. Now they have the formatting! Unless I'm going crazy, they did not have that when I first posted. Is there a time lag? If so, is there a way to preview how the post will look before posting?
