One thing: I do need to extend the user class somewhat, in order to add a couple of fields specific to my application. I've added the appropriate columns in the user table; where are the columns handled (i.e. what do I need to patch)?[/quote]

I think I've got this taken care of -- at first I was a bit confused because I was looking at the create_user function in the User model, but turns out I needed to edit the parameters of create_user (lines 157, 174) in the library itself. It seems strange to call the library which calls the model, rather than the other way around. Maybe this could be changed in a future version, to allow for greater extensibility?
