With ecoFeed you just open your RSS document directly. All news items as well as the channel info can be edited easily. Yet, ecoFeed aims for simple feeds, so currently no enclosures.
At startup it uses your AddressBook to get email address and a name for various RSS fields. Of course you still can change them. It is based on the document architecture and features automatic versions.
Feel free to contact us at ecoFeed @ ecoobs.com. We may be able to help.
