I'm not sure whether they're using Java or JavaScript, but at communities.msn.com, to post a thread, they have a MS Word like interface.

They have a toolbar that allows you to select fonts, sizes, bold, italic, bullet points, etc. And all the effects shows up in real time.

Is there a place where I could get that script? It's basically a simple web based text editor that works in real time, I get a feeling that it'll only work in IE, but still wanna try it out.
