If you visit a page that does not exist yet, the create link is always lower case. Since the name of the page becomes the title this is important.

eg, visit:

http://geekout.org.uk/posts/NewPage

Create link is:

http://geekout.org.uk/ikiwiki.cgi?page=posts%2Fnewpage&from=&do=create

Not:

http://geekout.org.uk/ikiwiki.cgi?page=posts%2FNewPage&from=&do=create

done
