Also when you are categorizing images, please add the episode category to the image~ Like a pic of Crash Course should have been categorized with Crash Course~ And please check your sentences, captalizing every word isn't needed at all~
I appreciate that you are helping the wiki so much, but there are some things that you should probably do differently.
1. If something occurs in all 5 seasons, don't bother adding season categories to it. Those categories are for things that are season-specific.
2. The episode categories are very helpful. However, when you make them, make sure that in addition to categorizing the page itself, you categorize every page that redirects to that page.
You can find a list of redirects to a particular page by using the toolbar on the bottom of the page, clicking "My Tools" and clicking "What links here." Everything that says "Redirect" is a redirect page.
