hey does anyone know how these blog comments work here(scroll to bottom of page):

Is the blog comments software only allowing one font style and if so, how does the blog comments software do this?

And Is there any open source blog comment editor software like tinyMCE but for blogs?

Split this from a thread about embedding fonts.

You can find many comments scripts at http://www.hotscripts.com - do some reading up :)
