Could do that, but prefer to stay as close to the standard (nominally) supported vB model as possible.

This is, after all, the (again, nominally) official support for RSS feeds and that's an important part of keeping members interested and involved. It would be great to know exactly what it can do -- and why, for example, the JS component supplies less than the RSS.

Thanks.
