When I go to the stream settings tab, I'm seeing nothing apart from the 'Save settings' button.
Is there something else I need to have done before I'll see options in there?
I was expecting to be able to choose for it to show streams from different parts of the site, different actions, that kind of thing.
You can make adjustments to which activities show up on different dashboards. For instance, if you are getting too many of a particular type of activity on your main control panel dashboard, you may want to hide it.
These can be changed in settings > dashboards.
