Serendipity Forums

Hi all
Does anyone know where I can find some information about the Serendipity plugin SERENDIPITY_EVENT_FORUM?
What I would like to know is........

Can the forum viewed totally within the blog itself?
Will a link to the forum appear in one of the sidebars?
What does the forum look like?

I expect the forum would be installed like any other plugin?

Thanks
Terry

Just as an example:
Have a look here http://board.s9y.org/viewtopic.php?f=2&t=19265
There also is a link in there about that forum discussed.
