Not so much is Notes/Domino related stuff subitted to the technical library on developerWorks lately. This used to be a good place to learn about development in Notes/Domino
This is applicable to the Notes and Administrator clients too, but I only get to pick one IdeaSpace. :(
As a 'relatively' new entrant to Notes design and administration (I've only been doing it for a few years off and on), I'm incredibly frustrated by the poor learning materials ...
