Re: format line spacing
It took me a while to understand that you'll often get an extra line if you use HTML. Normally when you code HTML, lines are controlled by P and BR tags but if you put your tags on new lines:
Hi BR
What's shakin BR
Nuttin BR
You'll get extra lines:
Hi BR
What's shakin BR
Nuttin BR
because Wiki sees the line feed and the BR and so you'll often get two. Also stray characters from pasted text will also add extra lines and other schmutz.
