Adding Forum directly to the Adoptables site

[Ozeuth]

Hey guys,
I have a bit of a question regarding my adoptables site, Krene: http://krene.byethost7.com/index I would like to build a forum inside the site itself (Without directing it to an outside forum via a link or adding a widget)

My idea was to build the forum in a page which is accessed by clicking "Community".

1. However, to give it prominence as a key feature of the site as opposed to a minor area, I want to make the sequence of the link parents displayed be "Home, Community, Adoptables, User CP, Explore". I noticed though that I can't do any editing to the link parents themselves or move their positions around.

2. Secondly, I'm not sure how to make a forum that is accessible upon clicking "community". Is this even possible? D: I imagine it'd involve alot of coding but I was hoping a script was already available for it.
