For those of you who aren't inclined to write all of the server code yourselves, I would strongly suggest that you consider using a reporting service like ScriptCanary. It's inexpensive and easy to use. In fact, the ScriptCanary service will be completely free until March 1, to encourage people to give it a try. Thanks to Dorian for sharing his innovative ideas with me.
