I need a textarea Plug in Now!

Hi,

I want to display a biography in a post, but I don’t want to have a HUGE page. I want to have a text-area.

Unfortunately the classic html <textarea> tag is too “classic”.

What I’ve found until now is this:
https://www.n-son.com/scripts/jsScrolling/example4.html
which for some reason does not work inside wordpress, although the required files are loaded (both css and js).

I wonder if there are any plugins to get the job done.
