Another pet peeve of mine is the hierarchy issue in many freebie contents.  Runtime and crucial DAZ folders shouldn't be nested within a primary vendor or character/prop-named folder, it simply confuses any program-based installer and frustrates new users when they hunt for installed content.  I have spent extra time rearranging files/folders within a zip file so that they install correctly.  And please, place any documentation into its own-labeled folder within a primary folder called Documentation.
