What you are trying to do, I think, is pull in the articles activity stream and list it in a column beside the forum activity stream? This can probably be achieved using the .load() JQuery method and a custom template. Custom modules can also be fairly easily written to be used with Site-Builder.
Well, I was planning on moving forward with this, but I see not even 24 hours after your request for help, you've
thrown in the towel. Thanks for the heads up. At least I'm not wasting my time. :up:
