If the name you use to write quizzes is PaulCrewe, then I can tell you that both of your quizzes are showing up in their alphabetical subcategories. If you are not a Gold Member, it may be a few more days before you can see them there, as pages refresh more infrequently for Gold Members. You can be assured that they are there, though, and being played.
If you have friends who are having trouble finding them, one method that works is to type the quiz title into a major search engine (eg Google). I have just found both of your quizzes using this method (though the 'Harvey Birdman' one needed your user name as well).
Hope this helps. (Spanishliz, FunTrivia editor)
