I've now added an extension to the Wiki that allows the addition of footnotes within the Wiki pages.

This works in the same was as on Wikipedia, giving you a little numbered footnote link next to your text which links to some footnotes located elsewhere on the page.

So it would look something like:
Some text [1]

To add a reference to some text is quite easy and can be done in two ways.

1, Adding footnotes to a wikipage that contains a single footnotes section at the bottom of the page.

To do this you add the actual footnotes within the body of your wikipage text using the <ref> tage. For example:
Code:
Some text <ref>this is a footnote.</ref>

And then place the location of the footnotes to be displayed on the page using the tag:
Code:
<references/>

Adding this together, using page code like this:
Code:
===A section heading===

Some text <ref>this is a footnote.</ref>

===Footnotes===
<references/>
Would produce the following on the finished Wiki page:
A section heading

Some text [1]

Footnotes
1. this is a footnote.
2, Grouping footnotes into differently named groups with the ability to locate them in different places on the page.

Taking this further you can use group names to place your footnotes into footnote groups. To do this you use the following:
Code:
Some text <ref group"footnotes">another footnotes</ref>
Then this footnote group can be displayed at any point in the page using:
Code:
<references group="footnotes"/>
See the CA Wiki page here and look at the memory section to see how grouped footnotes works.
