It's not a big issue, though it does make it a little more difficult to make lists that aren't actual lists, but I've noticed that paragraphs are only acknowledged in posts if they're double spaced. 

So
I
get
this
when
I only hit enter once.

But

it

works

if

I hit enter twice. 

It'd be nice if it worked single spaced too.

Also, thanks for doing this big update session. It's appreciated. :)
