I was able to use my limited Markdown knowledge to format my posts a little.

I could use a tiny repeated line of hyphens to separate a post horizontally into two - now, when I try, there's no line - in fact, the hyphens completely disappear.

I think that I accidentally landed on using hyphens to generate a separating line. Is there a new way to create such a line now?

Any idea why this might have perished? Maybe it was lost in an update...
