Thank you, Rene, that helps a lot! Storing a list of BMessage objects inside a list of BMessage objects makes a lot of sense to me. I'll make a BMessage for everything in my Settings class, then a BMessage for everything in my Feed class, and a BMessage for everything in my Item class. Then I'll add them all together and squash them FLAT into a settings file. Working with the Haiku API is a pleasure. :) Thank you! David
