I've been playing with LiveJournal and noticed they, too, have a rich text textarea widget. But when I tried the simplest thing that could possibly work:
<html> <head> <title>Rich text?</title> </head> <body> <form> <textarea rows="5" cols="20"></textarea> </form> </body> </html>
It did not work. If I turn on the richtext feature of LiveJournal and paste in text I copy from a webpage which includes links, LiveJournal pastes the links as well as the text and formatting; with my sample page I just get plain text.
Sadly, there are no files to download in spite of the project claiming to be mature.
I just want to figure out how LiveJournal's rich text widget works.
