Thanks to all who helped answer my last question.

Now I am trying to decided what sorting criteria I will use.  This program really gives me TOO MANY (dare I say that?) choices.
I find two places to "define" what a movie "is" in my data base... Genre and Tags
Obviously the Tags list is self defined, that is I can make it my own.  What about the Genre list?  If it can be modified How do I do this?  If it cannot, WHO decides what is listed there and would it be possible to make suggestions for future builds?

Thanks in advance for your answers and comments.
