Make a Link
This wiki uses a very simple type of language to display text and links on a page, it's called 'Wiki Syntax' and essentially means when you want to link to something you wrap the link in 2 square brackets at either end of the text.
The above is an example, Don't include spaces round the text you want to link or it won't work.
You will only see the brackets in the Editing view, when you submit the page they turn into active links.
