In what aspect would you use it? is it meant for displaying code? - as you can pretty much use the PHP code for that i believe.
it formats the text in a different way than other vb code! so when people want to leave a comment e.g. btw did you get my pm? as its off-topic they can use the vb code. [ot]I think its pretty cool[/ot]
