broken link for explanation of 'invite a fried'

In my account menu (upper right in the nav bar) there is a menu item named 'Invite a friend' (#general-invite).

The help text in the lightbox contains a link to 'http://blog.bitbucket.org/2012/09/18/refer-a-friend%E2%80%A6for-free-users/' - which leads to a 404 error.

Very likely the link should point to http://blog.bitbucket.org/2012/09/18/refer-a-friend-to-bitbucket-for-free-users/
