Funny. I figured there couldn't be that many Eugene Volokhs in the world. Wasn't sure it was the same guy though.
Btw, I'm using your Posting Form Enhancer and FrTreeviewer Greasemonkey scripts. They rock. One thing I'd change about the posting script, is to make the <p> work like the bold and italics tag in that it would close the </p>
I managed to get it working the way I wanted myself.
added:
addButton('P', 'p', 'paragraphs', 'p');
commented:
// addButton('P', wrap(addOnOwnLine, '
'),
// 'Adds a
tag at the cursor.', 'enter');
Now, if only I could figure out how to insert a "<br>" by pressing shift-enter, it would be mostly perfect!
