Phpbb

I want to install phpbb onto one of my sites.

Installing it is easy, I know how to do that, but what I want to do is have a login / register box appear on my front page (Not the front page of the forums, but the main page of the whole site)

Does anyone know of a plugin that will let me do this? I'm sure there are out there I just don't know where to look.

Cheers
