The Activity widget allows you to show every action performed by any member of the site or yourself on the web page itself, such as blogs, uploaded pictures, etc.
You can customise the title of the widget. Please note that this widget looks best either in its default position on the Welcome page or in the main section of any other page.
Option 1 - Default welcome page
Because the Activity stream is added to your Welcome page by default, we recommend you don't add it to the main area of this Welcome page because you will be duplicating content. If you don't want the default Welcome page as your homepage, have a look at this tutorial.
Option 2 - Main section of the page
