How do I edit an immutable page?

[pierce3]

One of the pages I'm trying to edit is https://wiki.ubuntu.com/PostBooksHowTo. However, I don't see an 'edit' button and the page is marked as immutable. I am logged into the site, so I'm not sure what I'm missing. Do I need to request permission?

Thanksm

Do you have a Launchpad id? Or may be you have a mis-match of usernames and passwords between Launchpad and Ubuntu SSO?

You won't be able to edit the wiki unless it is aware of your Launchpad id.

May be https://help.ubuntu.com/community/WikiGuide/Registration will help.

Perfect. That was it. Thank you very much.
