it is all custom work for phpbb.com
however, there is an extension for putting a banner in the header like here.
there was an extension for adding a menu like the one here but it never worked very well as an extension.
I believe there is still one that creates something similar.
have a browse of the extension forums and the extension database etc. to see what you may like.
I'm baaaaaccckkkk. still doing work on donation basis. PM your needs.
