One of the powerful things about a Wiki is the ability to collaboratively generate well structured and linked articles. If I make a statement that references another important idea, I can simply enclose that phrase in double square brackets - [[evocative word or phrase]] - and that phrase will be displayed as a link.

If you click on the link and that word or phrase does not yet exist as a wiki article, the wiki engine will propose that you search for that phrase in the site or create a new wiki page.

Also, every [[Freelink]] throughout the site is displayed at the 'Freelinks' link on the right. You can create or edit from there as well.

So, if you have an idea that's important, make it into a link using the double square bracket convention and either make a page, or leave it for the community. Wiki's make this easy, so give it a try.
