I like it. It works fine for me. I logged and pasted that address into my browser and I went to the page where I could create my personal RSS feed link. I pasted that new link into Safari and the feed showed up just fine.
Will you be adding any other options to that feed? I can get the url, title and description in the feed, but not the sponsor name or the category.
I noticed that the actual feed address contains my username and password in the url. I wonder if encrypting that, or replacing it with a unique identifier of another kind, might be a good security measure.
