Forum:Unneeded Categories

In my "absence" I have noticed tons of unneeded and confusing as to what their purpose could possibly be categories, why? Take a look at, it features people and episodes and possibly other things (I only slightly looked over it), why does it exist? Does it serve any purpose? I already tried asking about it here but no response. Also another unneeded category would be, do we really need a list of plants in the series? felinoel ~  (Talk)  16:22, September 19, 2009 (UTC)
