I assure you I would have noticed if the result of my Friday effort was something that didn't compile, rather than a service that seems to work just fine. I've reviewed about half the code so far and it seems quite reasonable.

For some reason I'm getting downvoted for trying to help, but regardless, if you can (and want to) post a transcript somewhere of some of these sessions that aren't working out, maybe some of us who are having more success can take a look and see what's up.
