just curious...

You know how some people on LJ always use a smaller font size, or a different color, or center their text or whatever--not just for posts but also for comments?  How do they do that?  I mean, I know you can mock it up with HTML tags, but do they really take the time to type out HTML tags every time they make a comment?  There's no rich text setting for comments as far as I can tell. It seems like it'd be a huge pain to break out the HTML constantly just so you can be seen as a speshul snowflake. Is there some "annoying pre-teen* mode" you can enable in the LJ control panel so that all your comments have unique special formatting?

*no offense intended to all the preteens in the world that actually have good judgment
