Editing permission?

[Mason Loring Bliss]

I want to edit typos on this page:

    https://help.ubuntu.com/community/MacBookPro11-1/Saucy

...but there's a big "Immutable Page" notice on it. I assume I need to
explicitly be given edit privs either for that page for generally - how do I
request these? Or did I just now by asking? :P

Thanks in advance for clues. Please reply off-list, as I am not subscribed.
