I need to display an activity stream on my homepage, but it needs to be an activity stream which is unique to the homepage. I figure maybe one way to go about this would be to make a user, the sole purpose of which is just to provide an activity stream that can be displayed there. However I’m not even sure how to go about this. I see that it is possible to add an activity stream to the home page, but I’m not having luck figuring out how to display a unique activity stream, or a specific user’s stream. Anyone know how to go about this? Or have a link that explains how?
