* The newbies wouldn't use it anyway, as they would be too in an "urgent" hurry all the time to be bothered to use it.
* As for me, I would just "[ CODE][/CODE ]" it by hand. Most of the trivial code example I post are typed out directly in the Quick Reply textarea anyway. Come on people, set an example...
So personally, I don't see the need for it. Maybe for some of the senior members, but I don't think I'd find a good use for it, other than a waste of good bandwidth.
