What I'm trying to do is hide the <br> in the textarea field. Not disable it, but only make it invisible for the user editing the content. (You can view the <br>'s by logging into the admin panel and clicking anywhere on the content).
Nice concept, I've seen it starting to crop up and I sort of like it for smaller less-content heavy site.
I'll take it as a mistake but the first and last libraries you've listed are both jQuery 1.3.2 following that you might want to upgrade to 1.4.x, it has some great new features.
So, it's nice, it's simply & I'm sure it'll be more than suitable for smaller sites where the Webmaster simply wants to easily edit their content.
