For the Scratch Wiki tags according to the sticky in Questions about Scratch it says you put [wiki] but the example creates a link to a page on Wikipedia. Since the forums can't figure out which link you are referring to, it goes to Wikipedia (most likely first one created as a tag). I think the [wiki] tags should be [swiki] instead. What does the Scratch Team think?

The guide is out of date. [wiki] links to the Scratch Wiki and [wp] links to Wikipedia.
For example, Scratch vs Scratch (programming language).

Sorry about that; I just updated it.
