The 'About us' link in the nav bar is not always available. Is that on purpose?
It's there after navigating to either Forum or Donate (where it's just called 'About'), but not with any of the other pages. Also, when navigating to Donate, the Donate link is replace by 'About'. This is not the case for any of the other pages though, i.e. they stay available even after navigating to the respective page.
