I have added support for friendly urls to this blog .

you can now access this article as http://blog.amias.og.uk/title/Friendly_URLs

Its best to use the numeric URLs for linking because if there are more than two articles with the same title only the first will be shown. Each page includes a link to itself in both formats at the top of the page . [P] is a permalink which uses the ID (best for automated systems) and [L] which uses the friendly url (best for passing the link between people)
