This site supports a 'wiki' method of creating links to new content.  All you need to do when authoring a page is surround some words with double square brackets like so:
[ (x2)    Some  Title Text     ] (x2)

After saving your content, the words in double brackets will automatically create a link to the content (if it exists by that title already), or to the edit window to add the content if it does not yet exist.

It takes more effort to explain than it does to use it.  Go ahead.  Create a new 'Collaborative Story', and surround a key phrase or topic that you want to elaborate on using the double-bracket syntax and you'll be able to quickly add that new content too.
