Trailbum,
Because when you type those codes without the periods, they work! And they also become invisible!
So if I were to type [s.ize=4] and [c.enter] without the periods -- they would not show and the instructions would not include the words to type. The only way I could think of to SHOW the codes was to alter them in some way.
Hey, while I'm here, I have a couple more days on my stats now...
