Re: Site Wide Activity in one page
I guess, you can use this approach
1.Create a page template and put site wide activity loop there instead of the normal page stuff.
2.Go to Pages->new ,create a page and assign this template
1.Create a page template
2.Make this page template widgitized and call the widget in the page content area
3.Create necessary widget enabling login in your functions.php
4.Go create a page use this template.
6.Go to appearance->widgets and assign sitewide activity widget
It should work
