to make things easier with navigation at the main-tabs and also within the Bread-Crumbs, I would suggest to skip the "Home"-button and make the "Forums" being the "Home" of the website.
Because clicking onto the "Home"-Tab within the Bread-Crumb-navigation, brings you back to the blue start-screen, which is rather annoying.......
BreadCrumb-navigation is currently only 2 levels deep, instead of showing all levels to help the user understand at which screen he currently is at.
For example, being at "Forums / What´s New" shows BreadCrumb "Home / Forums".
When the user is within the "Forums"-Tab / "What´s New", he does not see that he can still click onto the "Forums"-Tab again in order to get back to the Forums-Overview.
Currently, this is not very intuitive UI. But rather confusing.
