Thanks Joel. I really wasn't expecting you to clean that post up but thank you.
Do you have any idea why this is happening though?
It's only started about a week or two ago.
Paragraph breaks on original material almost always are omitted.
Double line spacing reverts to single.
Lists are run together, as you saw, whether original material or cut and pasted from other sources.
Item oneItem twoItem three(I've constructed this post with examples to see how it publishes).

Edit to add - looks like paragraph breaks were retained, except for the parenthetical following the list. Double line spacing disappeared.
