Get my forum to open up within my site

[career_guru]

I was given this link http://www.simplemachines.org/community/index.php?topic=19638.0 as the place to find instructions on how to get my forum to open up within my website.  I'm not sure it's the right info because the post commences by saying "In many cases, people want their forum to look like their main site.  To make this possible..."  What I'm wanting to do is get my forum to open within my website just like SMF's opens up in their website.

Any advice?

Also, I don't know if it's the right place for this, but it would be great if you could create an event in the calendar without having to relate it to one of your boards.

Thanks.
