So there is a chance here I might just be off my rocker in regards to what Multisite really means or intends to be. But I'm very interested in the concept of having your main site, and then the ability for members to sign up and create their own subsite.
The main site would then pull data such as recent posts, activity, etc from the subsites.
Unfortunately once 3.0 arrived and I looked around for tags that would do such a thing I found nothing. Now again, perhaps this is because I'm crazy and such a thing was never intended, nor possible. But to me it seems such an obvious set of tags to include.
I'm no coder by any means but I would think there ought to be ways to aggregate information from our subsites.
So for instance I have a site about personal mythology. As you can see it has a main blog, and then areas set up (but not working) to pull posts from the subsites. How can someone like me pull this off?
