del.icio.us and blogging

del.icio.us has an experimental feature that automatically posts daily entries to your blog. I said to myself “that’s the ticket” to making sure I meet my LIS 2600 blog entry requirements. Unfortunately, I’ve run into a technical glitch. I need the “full URL of the XML-RPC interface”. Huh? Looking in the help section of del.icio.us was no help at all. It seems other bloggers have asked for clarification regarding this feature, and this URL requirement, but there have been no answers.
