river2.root is a rewrite of the aggregator that shipped with Frontier/Radio for years. It needed a rewrite, since we learned a lot about RSS over time. It is a podcatcher, does realtime with the RSS cloud element.
scripting2.root is a rewrite of the blogging software I use for scripting.com. You can install it and run it. It also need a rewrite, as it had evolved over years with lots of additions and trial features that didn't pan out.
radio2.root, as its name implies, is a link-oriented group linkblog app. It's the blogging portion of Blork. I know that's confusing but that's the way the product came together. You can find instructions on setting up a blork server on the frontiernews site.
myPhotos.root downloads all your pictures from Flickr and uploads them to S3. Leave it running and you'll have copies of everything you flow through Flickr.
