Hello Lee.
No thanks -- I have still earned value from this site. I did quite a few 'video' tutorials to get up-to-speed on what DotNetNuke was and how to get things going. It may still continue to be useful.
And, for those still reading after my original question, here's the answer:
A module defintion for a settings page must have they key of 'Settings' --> EXACTLY <-- or it won't be found by the DNN framework.
Ditto for edit pages ... the must have a key of 'Edit'
I fluked out on Edit (named it right), but not on settings.
Thanks all!
John
