This forum is on a profile called 'community'. That's because in Jamroom the profile is the main location for everything.
So for this demo system, since we don't want to have a separate forum on every profile, or even many profiles, we created on single profile 'community' to be the housing location for the only forum on the site.
On your site, you can have multiple forums if you like, but they will always be found on a profile. That's the way Jamroom CMS works.
