There's a few things that need polish .. I fixed a couple of small things and filed some bugs and feature requests on the others.
- Editing button on each Wiki page
- The first page is called WikiIndex ... is this hardcoded?
- On wiki editing page, remove the "CancelEditing" link in favour of a Cancel Editing button
- "Wiki already has entries - can't change"
- Wiki at site level requires login (it shouldn't)
- Deleting a wiki at site level gives errors
- More wiki strings and help pages need to be internationalised
