I have just recently noticed that there are 2 categories which are of the same meaning. Category:Mode and Category:Modes. These 2 categories contain almost the exact same articles(except for Night, which isn't even a mode). "Modes" is just the plural form of "Mode".
I would suggest deleting either one of these categories in order to avoid confusion that readers may have when navigating this wiki.
However, I am unsure of which category should be deleted and would thus, like to ask you all which one should be removed. I am just a registered user and I don't have the permission to remove articles like category pages.
For the convenience of you administrators, I have created a vote poll so as to let the public decide which category should best be removed. To vote, simply click one of the radio buttons and then click "Vote!".
