Create A Forum - Support Forums

Howdy all, I'm a noob here.  Some friends and I are building a new forum for our gaming clan and would like to add a chat wall, not a simple shoutbox but a full blown chat wall.  I understand there is something like that for a $30 one time fee.  That being said, is there a way we can demo this chat function or possibly see a forum that has one running so we can decide if it will work for us and do what we want. 

Thank you in advance.  Any information is greatly appreciated.
