The main issue was that that all the optional fields weren't defaulting to the correct option. This was most obvious in the "type" field was defaulting to "rss" rather than "text"! I've also fixed the About page so that now works too

In terms of ordering of items, the only options are alphabetically or most recent first. I'll look at some sort of "hard coded" ordering in another version.
Let me know if there's any other show stoppers!
