Re: Group Activity on a Site
Not sure if there’s a template tag for this yet, but I’d go with the activity stream widget (plugin) http://buddydev.com/buddypress/buddypress-sitewide-activity-widget-for-buddypress-1-2-and-above/ … it’s still a work in progress since you can’t post directly from it (only through your profile), but it works right out of the box.
