That's truly great, Badger, can't wait to see them.
That would be the equivalent of being able to publish ezine mini-sites.
While your guys are in this innovative development cycle, may I also suggest that they create an optional mailing list subscription feature. In fact I don't mind paying a small fee for using that feature.
The mailing list can be double-opt-in. The value of a mailing list can be enormous, especially for content (e.g. ezine) publishers and the convenience of their readers.
