= Editing FAQs =

It is possible to modify the title, keywords and content of an existing
FAQ. To do this, the user goes to the FAQ that he wants to modify and
clicks the 'Edit FAQ' action.

That action is only available to project owners and answer contacts.
That's why the link doesn't appear for the anonymous user nor
No Privileges Person:

    >>> from lp.services.helpers import backslashreplace
    >>> anon_browser.open('http://answers.launchpad.dev/firefox/+faq/7')
    >>> print backslashreplace(anon_browser.title)
