It would be extremely kind of the administrator to make ALL of the forums public.
The Forum Quick Jump drop down in the upper right corner leads one to believe
they are all public anyway.
I belong to many forums and most if not all are open to the public for viewing.
Then the only time one has to "log in", is when you wish to reply or start a new topic.
The login page doesn't handle auto completion or seem to have the ability to remember
passwords as soon as you enter your username.
The "log in" requirement just to view new posts seems very unnecessary.
all the best,
