When you paste into the blogspot text box, you can only paste the text. There's nothing you can do about that - you have to type any formatting codes in yourself, using whatever convention blogspot uses. It's often not HTML, unlike Mudcat which allows (limited) HTML codes in the text box.

"They can't ALL be composing in those post boxes (without good editing capabilities) and then publishing"

You could compose in a decent text editor (NOT a word processor) but other than that, the answer is yes - they probably are!

I like Notepad2, a perfect replacement for Windows notepad.
