Click the main AFI/DF banner at the top. Should take you to the portal. Not sure if I'd like to request a more obvious way to access the forums from the new home page... it won't matter in two weeks when it's second nature but I was just really confused how to when it changed over.
Looking at it now it's kind of logical where the link is... but I generally don't look at the clutter parts when looking for a main item link.
