If you scroll down the web page, you get the MWO/Media/Forums/Community/Support menu options again.
This is on all browsers I've tested it with (Chrome/IE/Firefox).

Ahhh - I've just realised it appears to be by design. The large block menu "folds up" to the smaller one when you're scrolled.
Bad design imho - not intuitive.
