BuddyPress.org

I see that one of the CUNY Academic Commons groups has a tab that another group does not:

http://commons.gc.cuny.edu/groups/games-teaching-and-learning/ – has a “Visit Blog” tab

http://commons.gc.cuny.edu/groups/gc-comp-rhet-area-group/ – does not have a “Visit Blog” tab

This makes is seem as if it is possible to show different tabs to different groups within a single BuddyPress installation, but I want to confirm whether this can be applied to all different types of tabs or if it is functionality that is specific to the blog that can be tied to a specific BP group.

Thanks,
Adam
