BBPress 2º Integration

Hello,

My forum setup in buddypress for my site is:

"bbPress forum integration in BuddyPress has been set up correctly"

"Disable global forum directory?: yes"

"Activates bbPress forum support within BuddyPress groups or any other custom component: Enable"

I have forum function for groups, but i want i a new bbpress forum in another page, like:

http://www.pokermadeira.com/forum (forum folder don't exist yet)

Since i have bbpress installed with my buddypress installation, can i have a second buddypress installation, sharing the same database and users like explained in this video?:
